1.泛型算法:
大多数算法定义在头文件algorithm中,标准库还在头文件numeric中定义了一组数值泛型算法
举例:
find函数用于找出容器中一个特定的值,有三个参数
int val = 10;//val为我们需要查找的值
auto result = find(vec.begin(), vec.end(), val):
cout
find将前两个表示范围的迭代器内的元素与va...

题目:For example, given s = "aab",
Return 1 since the palindrome partitioning ["aa","b"] could be produced using 1 cut
解题思路:给一个字符串,如果字符串可以划分成若干子回文字符串,返回最小的划分数量。
这个题如果还用之前求所有划分组合的循环加递归方法的话,就会得到超时的错误。这是就要考虑别的方法,动态规划倒是一个不错的方法,但是动态规划最重要的是要找到动态方程。本题的动态方程:
dp[i] =...

Given s1, s2, s3, find whether s3 is formed by the interleaving of s1 and s2.
For example,
Given:
s1 = "aabcc",
s2 = "dbbca",
When s3 = "aadbbcbcac", return true.
When s3 = "aadb...
