LeetCode Best to buy and sell stock
Best Time to Buy and Sell Stock
题目大意;给定数组a[..],求解max a[j]-a[i] j>i
解决思路:将数组a的相邻值相减(右边减左边)变换成数组b,上述问题
转变成了求数组b的子数组最大和问题。
public int maxEndingHere=0,maxSoFar=0;
for (int k=0;k<n;k++){
int s=0;
int t=n-1;
while (s<t){
int tmp=matrix [k][s];
matrix[]k][s]=martix[k][t];
matrix[k][t]=tmp;
s++;
t--;
}
}
return ;
}
};
