2270. Number of Ways to Split Array

Leetcode Solutions

Prefix Sum Approach

  1. Initialize a variable to store the total sum of the array elements.
  2. Calculate the total sum by iterating through the array.
  3. Initialize a variable to store the prefix sum, initially set to 0.
  4. Initialize a counter to keep track of the number of valid splits, initially set to 0.
  5. Iterate through the array, stopping at the second to last element. a. Add the current element to the prefix sum. b. Subtract the current element from the total sum to get the sum of the remaining elements. c. If the prefix sum is greater than or equal to the sum of the remaining elements, increment the valid split counter.
  6. Return the valid split counter.
