WebMar 16, 2024 · An efficient solution is based on below observation. Let there be a subarray (i, j) whose sum is divisible by k sum (i, j) = sum (0, j) - sum (0, i-1) Sum for any subarray can be written as q*k + rem where q is a quotient and rem is remainder Thus, sum (i, j) = (q1 * k + rem1) - (q2 * k + rem2) sum (i, j) = (q1 - q2)k + rem1-rem2 We see, for ... WebWe can use multimap to print all subarrays with a zero-sum present in the given array. The idea is to create an empty multimap to store all subarrays’ ending index having a given sum. Traverse the array and maintain the sum of elements seen so far. If the sum is seen before, at least one subarray has zero-sum, which ends at the current index.
