WebJun 14, 2024 · Since the array may hold up to 20,000 elements, then the sum can be as large as ±1000 * 20000 = ±20,000,000. Again std::int_fast32_t is suitable here. For the number of subarrays, the extreme case would be an input of 20,000 zeros, and a target of zero, making ½ * 20000 * 10000 = 100,000,000 matching subarrays. WebSolution 2: Lets say array is arr [] and given sum is X. Iterate over array arr []. If currentSum is less than X then add current element to currentSum. If currentSum is greater than X , it means we need to remove starting elements to make currentSum less than X. If CurrentSum is equal to X, we got the continuous sub array, print it.
