Min dan max merupakan salah satu atribut yang ada di bahasa pemograman HTML. Fungsi dari atribut min dan max adalah memberi batas minimum dan maksimum yang boleh diinputkan. Min dan max digunakan untuk menginput angka, sedangkan pada inputan teks min dan max tidak akan bekerja. Dalam penggunaan atribut min dan max, kita dapat mengatur input. In this example, min represents the minimum value the field will accept, and max represents the maximum value. If we reach the maximum or minimum value, the appropriate arrow on the spinbox control will be greyed out so you can no longer interact with it. Step is the increment that the value should adjust up or down, with the default step value. This article brings you a very interesting and lesser known function of Python, namely max and min.Now when compared to their C counterpart, which only allows two arguments, that too strictly being float, int or char, these functions are not only limited to 2 elements, but can hold many elements as arguments and also support strings in their arguments, hence allowing to display. Rescaling (min-max normalization) Also known as min-max scaling or min-max normalization, is the simplest method and consists in rescaling the range of features to scale the range in 0, 1 or −1, 1. Selecting the target range depends on the nature of the data. The general formula for a min-max of 0, 1 is given as.

Find the minimum and maximum value in an array

Difficulty: Medium

Asked in: Facebook

Understanding the Problem

Problem Description: Given an array A[] of size n, you need to find the maximum and minimum element present in the array. Your algorithm should make the minimum number of comparisons.

For Example:

Input: A[] = { 4, 2, 0, 8, 20, 9, 2}

Output: Maximum: 20, Minimum: 0

Input: A[] = {-8, -3, -10, -32, -1}

Output: Maximum: -1, Minimum: -32

Possible follow-up questions to ask the interviewer :-

1. Are the array elements necessarily positive? (Ans: No, they can be positive, negative, or zero)
2. Are the array element sorted ? (Ans: No, they can be in any order)
3. Can the array contain duplicates? (Ans: Sure, that's a possibility.)

Problem Note:- The interviewer would not judge your algorithm for this question based on the time complexity as all solution has the time complexity of O(n). The bottleneck parameter in this problem is the number of comparisons that your algorithm requires to determine the maximum and the minimum element. You need to decrease the number of comparisons as much as you can.

Solutions

1. Searching linearly: Increment the loop by 1
2. Divide and Conquer: Tournament Method
3. Comparison in pairs: Increment the loop by 2

1. Searching linearly: Increment the loop by 1

We initialize both minimum and maximum element to the first element and then traverse the array, comparing each element and update minimum and maximum whenever necessary.

Pseudo-Code

Complexity Analysis

At every step of the loop, we are doing 2 comparisons in the worst case. Total no. of comparisons (in worst case) = 2*(n-1) = 2n - 2

Time complexity = O(n), Space complexity = O(1)

In the best case, a total of n-1 comparisons have been made. (How?)

Critical ideas to think!

• We have initialized maximum and minimum with the first element of the array - why?
• What would be the best case and worst case input?
• How can we decrease the number of comparisons made here?

2. Divide and Conquer : Tournament Method

Another way to do this could be by following the divide and conquer strategy. Just like the merge sort, we could divide the array into two equal parts and recursively find the maximum and minimum of those parts. After this, compare the maximum and minimum of those parts to get the maximum and minimum of the whole array.

Solution Steps

1. Write a recursive function accepting the array and its start and end index as parameters
2. The base cases will be

• If array size is 1, return the element as both max and min
• If array size is 2, compare the two elements and return maximum and minimum

3. The recursive part is

• Recursively calculate and store the maximum and minimum for left and right parts
• Determine the maximum and minimum among these by 2 comparisons

4. Return max and min.

Pseudo Code

Complexity Analysis

For counting the number of comparisons, since this is a recursive function, let us define the recurrence relation :

Time complexity = O(n) and space complexity = O(logn) (For recursion call stack)

If n is a power of 2, the algorithm needs exactly 3n/2–2 comparisons to find min and max. If it's not a power of 2, it will take a few more(not significant).

Critical ideas to think!

• How do we analyze the recursion by the master's theorem and recursion tree method?
• How is the space complexity derived to be O(logn)?
• Why there are 2 base cases? What if we remove the base case with array size 2?
• Why prefer mid = start + (end - start)/2 over (start + end)/2 when calculating middle of the array ?
• Can the number of comparisons be decreased further?

3. Comparison in Pairs : Increment the loop by 2

In this approach, we pick array elements in pairs and update the min and max. If the array size is odd, we initialize the first element as both min and max, and if it's even, we compare the first two elements and initialize min and max accordingly.

Solution Steps

1. Create max and min variables.
2. Check for the size of the array

• If odd, initialize min and max to the first element
• If even, compare the elements and set min to the smaller value and max to the bigger value

3. Traverse the array in pairs

4. For each pair, compare the two elements and then

• Compare the bigger element with max, update max if required.
• Compare the smaller element with min, update min if required.

5. Return max and min.

Pseudo Code

Complexity Analysis

Time Complexity is O(n) and Space Complexity is O(1).

For each pair, there are a total of three comparisons, first among the elements of the pair and the other two with min and max.

Total number of comparisons:-

• If n is odd, 3 * (n-1) / 2
• If n is even, 1 + 3*(n-2)/2 = 3n/2-2

Critical ideas to think!

Input Min Max React

• Why min and max are initialized differently for even and odd sized arrays?
• Why incrementing the loop by 2 help to reduce the total number of comparsion ?
• Is there any other way to solve this problem? Think.
• In which case, the number of comparisons by method 2 and 3 is equal?

Scale with Parameters (SCP)
[Command Table][Main Course Page][Group Index]

The SCP instruction is used to produce a sealed output value that has a linear relationship between the input and scaled values. The input value is scaled to a range determined by creating a linear relationship between input min and max values and scaled min and max values. It recognizes the use of integer and floating point values. This command can be used with SLC 5/03 OS302 and SLC 5.04 OS401 processors.

The following formula will convert analog input to data to engineering units:

y = mx + bWhere:y = scaled outputm = slope (scaled max. -scaled min.)/(input max. -input min.)x = input valueb = offset (y intercept) = scaled min - (input min. X slope)

Note:

The Input Minimum, Input Maximum, Scaled Minimum, and Scaled Maximum are used to determine the slope and offset values. The input value can go outside of the specified input limits and no ordering is required. For example, the scaled output value will not necessarily be clamped between the scaled minimum and scaled maximum values.

Entering Parameters:

The following parameters are necessary when programming this instruction:

Input value- a word or address of floating point data elements.

Input Minimum and Input Maximum- values determine the range of data that appears in the Input Value parameter. The value can be a word or address, and integer constant, floating point data element, or floating point constant.

Javascript Input Min Max

Scaled Minimum and Scaled Maximum- values determine the range of data that appears in the Scaled Output parameter. The value can be a word address, an integer constant, floating point data element, or a floating point constant.
