[LeetCode] 1155. Number of Dice Rolls With Target Sum

1155. Number of Dice Rolls With Target Sum Medium You have n dice and each die has k faces numbered from 1 to k. Given three integers n, k, and target, return the number of possible ways (out of the kn total ways) to roll the dice so the sum of the face-up numbers equals target. Since the answer may be too large, return it modulo 109 + 7. Example 1: Input: n = 1, k = 6, target = 3 Output: 1 Expl..
