答案仅供参考（不是最优解） #include <bits/stdc++.h> using namespace std;

string jiami(char x) { if (x == '3' || x == '4' || x == '7' || x == '8') { std::string s = ""; s = x; return s; } else if (x == '0') { return "o"; } else if (x == '1') { return "l"; } else if (x == '2') { return "z"; } else if (x == '5') { return "s"; } else if (x == '6') { return "b"; } else if (x == '9') { return "q"; } return ""; }

int main(void) { freopen("man.in","r",stdin); freopen("man.out","w",stdout); string a; cin >> a ; for (long long i = 0; i < a.size(); i++) { a.replace(i, 1, jiami(a[i])); } printf("%s", a.c_str()); return 0; }
