Binary arrays and sliding sums
WebMar 12, 2024 · Subarray with given sum is: 1 9. 3 7. Time Complexity: O (n^2 + n), because we need to generate all possible subarrays. This contributes O (n^2) and printing the subarray takes O (n). As a result, O (n^2 + n) ~ O (n^2). Space Complexity: O (1), we are not using any extra space.
