Subarray

Maximum Subarray

先用一种类似动态规划的蛮力法，超时了：publicintmaxSubArray(int[]nums){ intsum=nums[0]; for(inti=1;i=0;j--){ temp+=nums[j]; if(temp>sum) sum=temp; } } returnsum; }后来想到了二分法。这个最大值要么包括nums[mid]，要么就是在mid的左边或者右边。要考虑到细节，不然就会出错

subarray、subsequence的区别

subarray是截取数组中连续的一段子数组。subsequence是序列中不连续的一段子序列。[1,2,3,4,5,6]subarray=[3,4,5];subsequence=[2,4,5];

f(j+1)为以下标j结尾的连续子序列最大乘积值（1）状态转移方程如何表示呢：这里我们知道A[j]可能为正数(或0)或负数，那么当A[j]为正数，期望前j个乘积为正数，若为负数，则期望前面的为负数。故我们需定义两个函数来确定我们的状态转移方程：fmax(j+1)=max(max(fmax(j)∗A[j],A[j]),fmin(j)∗A[j])fmin(j+1)=min(min(fmin(j)∗A[

和53.MaximumSubarray是一个思路，所以在一起做了，主要就是维护一个局部最优和一个全局最优。不同在于，因为是有正负数，负号会导致上一轮的最小可能在这轮成为最大的，所以每一次不仅要记录一个局部最大解，还要记录一个局部最小解。1publicintmaxProduct(int[]nums){ 2if(nums==null||nums.length==0){ 3return0; 4}
