2395. Find Subarrays With Equal Sum

Leetcode Solutions

Using a Hash Map to Track Subarray Sums

  1. Initialize an empty hash map to store the sums of subarrays of length 2.
  2. Iterate through the array from the first element to the second-to-last element.
  3. For each index i, calculate the sum of nums[i] and nums[i+1].
  4. Check if the calculated sum is already in the hash map.
    • If it is, return true because we have found two subarrays with the same sum.
    • If it is not, add the sum to the hash map.
  5. If the end of the array is reached without finding duplicate sums, return false.
