Closest Sum Problem Statement

Given an array of integers ARR of size N and an integer target, find three integers in ARR such that their sum is closest to the target. If there are two closest sums, return the smallest sum.

Input:

The first line contains an integer 'T' denoting the number of test cases. For each test case: - The first line contains an integer 'N', the size of the array. - The second line contains 'N' space-separated integers representing the array. - The third line contains an integer, the target.

Output:

For each test case, output the sum of the triplet that is closest to the target on a new line.

Example:

Input:

ARR = [1, 2, 3, 4, 5], target = 10

Output:

9

Constraints:

1

Closest Sum Problem Statement

Given an array of integers ARR of size N and an integer target, find three integers in ARR such that their sum is closest to the target. If there are two closest sums, return the smallest sum.

Input:

The first line contains an integer 'T' denoting the number of test cases.
 For each test case:
 - The first line contains an integer 'N', the size of the array.
 - The second line contains 'N' space-separated integers representing the array.
 - The third line contains an integer, the target.

Output:

For each test case, output the sum of the triplet that is closest to the target on a new line.

Example:

Input:

ARR = [1, 2, 3, 4, 5], target = 10

Output:

Constraints:

1 <= T <= 10
3 <= N <= 100
-10⁵ <= ARR[i] <= 10⁵
-3 * 10⁵ <= target <= 3 * 10⁵

Note:

You are not required to print anything; just implement the function as directed.

Accepted Answer

The task is to find three integers in an array whose sum is closest to a given target.

Iterate through all possible triplets in the array to find the closest sum to the target.
Keep track of the closest sum found so far and update it if a closer sum is found.
Return the closest sum found after iterating through all triplets.

Accepted Answer

Two - Pointer Approach By sorting the array the efficiency of the algorithm can be improved. This efficient approach uses the two-pointer technique. After sorting the array, traverse the array and f...read more
