# Guess the number

AekdyCoin is the most powerful boy in the group ACM_DIY, whose signature is valuable. In order to get his signature, you must first solve this problem. But don’t be worried, because this is the easiest problem in the world. You are given only one sentence written in English. You are asked to output a single integer implied by this sentence.

There is only one line in the input. It is a sentence which implies some integer. The length of the sentence is no more than 16. The sentence contains only letters(both uppercase and lowercase), digits, and whitespace. You may assume the given sentence is written in standard English, and always implies exactly one single integer.

#include <cstdio>

using namespace std;

int main(){
printf("%d\n", 'H');

return 0;
}

1. for(int i=1; i<=m; i++){
for(int j=1; j<=n; j++){
dp = dp [j-1] + 1;
if(s1.charAt(i-1) == s3.charAt(i+j-1))
dp = dp[i-1] + 1;
if(s2.charAt(j-1) == s3.charAt(i+j-1))
dp = Math.max(dp [j - 1] + 1, dp );
}
}
这里的代码似乎有点问题？ dp(i)(j) = dp(i)(j-1) + 1;这个例子System.out.println(ils.isInterleave("aa","dbbca", "aadbbcb"));返回的应该是false

2. 问题3是不是应该为1/4 .因为截取的三段，无论是否能组成三角形， x， y-x ，1-y,都应大于0，所以 x<y,基础应该是一个大三角形。小三角是大三角的 1/4.
