Leetcode Solutions

Prefix Sum Approach

  1. Initialize minSum to 0 and currentSum to 0.
  2. Iterate through each number in the nums array. a. Add the current number to currentSum. b. Update minSum to be the minimum of minSum and currentSum.
  3. If minSum is less than 0, return 1 - minSum as the minimum starting value. This ensures that the running sum will be adjusted to never drop below 1.
  4. If minSum is 0 or positive, return 1 as the minimum starting value.
