傳回字元串的逆序
原文
Write a function that takes a string as input and returns the string reversed.
Example:
Given s = “hello”, return “olleh”.
翻譯
寫一個函數,以一個字元串作為輸入,并逆序傳回。
例如:
給定s = “hello”,傳回”olleh”。
代碼
直接逆序周遊
string reverseString(string s) {
string result;
for (int i = s.length() - 1; i >= 0; i--) {
result += s[i];
}
return result;
}
使用STL
string reverseString(string s) {
reverse(s.begin(), s.end());
return s;
}
