判断最后一个字符

解题思路:

注意事项:

参考代码:

#include<bits/stdc++.h> 

using namespace std;

int main(){

string s1,s2;

cin>>s1>>s2;

int count=0,p,num=0;

int min=s1.length();

int max=s2.length();

if(s2.length()<s1.length()){

min=s2.length();

max=s1.length();

}

if(s1[s1.length()-1]==s2[s2.length()-1]){

for(int i=0;i<min;i++){

if (s1[i]==s2[i]){

p=i;

}

}

num=max-2-p;

for(int i=0;i<=p;i++){

if (s1[i]!=s2[i]){

count++;

}

}

}else{

for(int i=0;i<min;i++){

if (s1[i]!=s2[i]){

count++;

}

}

}

cout<<num+count;

return 0;

}
