How do you find the smallest difference in an array?

How do you find the smallest difference in an array?

Below are steps.

1. Sort array in ascending order. This step takes O(n Log n) time.
2. Initialize difference as infinite. This step takes O(1) time.
3. Compare all adjacent pairs in sorted array and keep track of minimum difference. This step takes O(n) time.

How do you count pairs in C++?

Method 2 (Use Sorting) 1) Initialize count as 0 2) Sort all numbers in increasing order. 3) Remove duplicates from array. 4) Do following for each element arr[i] a) Binary Search for arr[i] + k in subarray from i+1 to n-1. b) If arr[i] + k found, increment count.

How do you find the largest and smallest number in an array in C?

Iterative program to find the smallest and largest elements in an array

1. / C program to find the smallest and largest element in an array. ​
2. int main() {
3. printf(“\nEnter the number of elements : “); scanf(“%d”,&n);
4. printf(“\nInput the array elements : “);
5. scanf(“%d”,&a[i]);
6. large=small=a[0];
7. for(i=1;i
8. large=a[i];

How to find the smallest difference between two arrays?

Smallest Difference pair of values between two unsorted Arrays. Given two arrays of integers, compute the pair of values (one value in each array) with the smallest (non-negative) difference. Return the difference. Examples : A simple solution is to Brute Force using two loops with Time Complexity O(n 2). A better solution is to sort the arrays.

How to find the second minimum element in an array?

Find the second minimum element from the array and store it in secondMin. Print min + secondMin. Below is the implementation of the above approach: import java .io.*;

Which is the smallest difference between two unsorted values?

Well, the value at bis bigger than the value at a, so moving b will only make the difference larger. Therefore, we want to move a. 3. Now a points to 2 and b (still) points to 4. This difference is 2, so we should update min. Move a, since it is smaller.
