Subarray Sum Finder Solution

Explanation: Step-by-step: We start with the array [1, 2, 3, 4, 5] and the target sum 6. We use a hashmap to store the cumulative sum and its frequency. We iterate through the array, and for each element, we check if the hashmap contains the cumulative sum minus the current element. If it does, we increment the count by the frequency of the cumulative sum minus the current element. We update the hashmap with the new cumulative sum and its frequency. Finally, we return the count of subarrays with sum 6.

Explanation: Step-by-step: We start with the array [5, 5, 10] and the target sum 10. We use a hashmap to store the cumulative sum and its frequency. We iterate through the array, and for each element, we check if the hashmap contains the cumulative sum minus the current element. If it does, we increment the count by the frequency of the cumulative sum minus the current element. We update the hashmap with the new cumulative sum and its frequency. Finally, we return the count of subarrays with sum 10.
