问题简介 本文将介绍计算机算法中的经典问题——最大子数组问题(maximum subarray problem)。所谓的最大子数组问题,指的是:给定一个数组A,寻找A的和最大的非空连续子数组。比如,数组 A = [-2, -3, 4, -1, -2, 1, 5, -3], 最大子数组应为[4, -1, -2, 1, 5],其和为7。 首先,如果A中的元素全部为正(或非负数)
Step 2.1 If the maximum subarray does not contain the middle element, then we can apply the same algorithm to the the subarray to the left of the middle element and the subarray to the right of the middle element. Step 2.2 If the maximum subarray does contain the middle element, then the...
Here, acircular arraymeans the end of the array connects to the beginning of the array. (Formally,C[i] = A[i]when0 <= i < A.length, andC[i+A.length] = C[i]wheni >= 0.) Also, a subarray may only include each element of the fixed bufferAat most once. (Formally, for a ...

53. Maximum Subarray Given an integer arraynums, find the contiguous subarray (containing at least one number) which has the largest sum and return its sum. Example: Input: [-2,1,-3,4,-1,2,1,-5,4], Output: 6 Explanation: [4,-1,2,1] has the largest sum = 6....

Can you solve this real interview question? Number of Subarrays with Bounded Maximum - Given an integer array nums and two integers left and right, return the number of contiguous non-empty subarrays such that the value of the maximum array element in th
Given acircular integer arraynums of length n, returnthe maximum possible sum of a non-emptysubarrayofnums. Acircular arraymeans the end of the array connects to the beginning of the array. Formally, the next element of nums[i] is nums[(i + 1) % n] and the previous element of nums...
Here, a circular array means the end of the array connects to the beginning of the array. (Formally, C[i] = A[i] when 0 <= i < A.length, and C[i+A.length] = C[i] when i >= 0.) Also, a subarray may only include each element of the fixed buffer A at most once. (For...
