Problem
Write a function that takes a string as input and returns the string reversed.
Example
Input: "hello"
Output: "olleh"
Input: "A man, a plan, a canal: Panama"
Output: "amanaP :lanac a ,nalp a ,nam A"
Code
static int var = [](){
std::ios::sync_with_stdio(false);
cin.tie(NULL);
return 0;
}();
class Solution {
public:
string reverseString(string s) {
string res = "";
for(int i=s.size()-1;i>=0;i--)
res += s[i];
return res;
}
};
Result
