数组类算法解题思想

当要解决一个求一个数组里面具有某种性质的一组元素,可以加个限制条件,比如以第i个结尾的子序列的这种性质,求出n个结果,而

最终答案一定落在这n个数字里面,遍历一遍就可以了。 

示例:

Given an integer array nums, 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.
