WebMinimum Size Subarray Sum. Given an array of n positive integers and a positive integer s, find the minimal length of a contiguous subarray of which the sum ≥ s. If there isn't one, return 0 instead. For example, given the array [2,3,1,2,4,3] and s = 7, the subarray [4,3] has the minimal length under the problem constraint. Web29 mei 2024 · Naive Approach: A naive approach is to replace all possible positive sub-arrays with the values which we get by dividing it by X and compute the sum. But the total number of sub-arrays for any given array is (N * (N + 1))/2 where N is the size of the array. Therefore, the running time of this algorithm is O(N 2). Efficient Approach: This problem …

We can then simply find the largest j <= M such that dp [K] [j] is true. Our base case dp [0] [0] = true because we can always make a subset that sums to 0 by picking one of size 0. The recurrence is also fairly straightforward.
