then the underlined subarray would be the one we are looking for (its "score" is 7×4 = 28) . Notice that if we changed "sum" into "min" the problem would be solvable in time. Similarly, if we changed "sum" into "gcd" the problem would still be solvable in ...
problem: Find the contiguous subarray within an array (containing at least one number) which has the largest sum. For example, given the array [−2,1,−3,4,−1,2,1,−5,4], the contiguous subarray [4,−1,2,1] has the largest sum = 6. ...
Can you solve this real interview question? Maximum Product Subarray - Given an integer array nums, find a subarray that has the largest product, and return the product. The test cases are generated so that the answer will fit in a 32-bit integer. E
Can you solve this real interview question? Maximum Average Subarray I - You are given an integer array nums consisting of n elements, and an integer k. Find a contiguous subarray whose length is equal to k that has the maximum average value and return
subarray and the minimum subarray problems. Themaximum subarray problemis to find the contiguous subarray having the largest sum. Likewise, the minimum subarray problem is to find the contiguous subarray having the smallest sum. Variants of Kadane’s algorithm can solve these problems in O(N) ...
