Problem: Minimum Operations to Reduce X to Zero

med
30 min
Try to solve the Minimum Operations to Reduce X to Zero problem.

Statement

You are given an integer array nums and an integer x. In each operation, you can remove either the leftmost or the rightmost element from the array nums and subtract its value from x. This removes the element from the array for any subsequent operations.

Return the minimum number of operations required to reduce x to exactly 00. If it is impossible to reduce x to 00, return −1-1.

Constraints:

  • 1≤1 \leq nums.length ≤105\leq 10^5

  • 1≤1 \leq nums[i] ≤104\leq 10^4

  • 1≤1 \leq x ≤109\leq 10^9
