挨个儿对着比就行，暴力。

#include <iostream>#include <string>using namespace std;int main(){    string a, b;    while (cin>>a>>b) {        unsigned long i, j, len1, len2;        len1 = a.length();        len2 = b.length();        i = j = 0;        while (true) {            if (i == len1) {                cout << "Yes" << endl;                break;            }            else if (i < len1 && j == len2)            {                cout << "No" << endl;                break;            }            if (a[i] == b[j]) {                i++;j++;            }            else j++;        }    }    return 0;}
