Solution: Number of Divisible Triplet Sums

C# solution for the Number of Divisible Triplet Sums problem using the Hash Maps pattern.

Statement

Given an integer array nums and an integer d, count how many index triplets (i, j, k) satisfy all of the following conditions:

The indices are strictly increasing: i < j < k.

The sum nums[i] + nums[j] + nums[k] is divisible by d, meaning (nums[i] + nums[j] + nums[k]) % d == 0.

Return the total number of such triplets.

Constraints:

  • 11 \leq nums.length 1000\leq 1000

  • 11 \leq ...
