1658. Minimum Operations to Reduce X to Zero
Problem Statement
You are given an integer array nums
and an integer x
. In one operation, you can either remove the leftmost or the rightmost element from the array nums
and subtract its value from x
. Note that this modifies the array for future operations.
Return the minimum number of operations to reduce x
to exactly 0
if it is possible, otherwise, return -1
.

Example 3:
Constraints:
1 <= nums.length <= 105
1 <= nums[i] <= 104
