Solution in C++ using STL std::swap:

void reverseString(vector<char>& s) {
for (std::size_t i = 0; i < s.size() / 2; ++i) {
std::swap(s[i], s[s.size() - 1 - i]);
}
}
Note that only half of the string is traversed in the loop.

thanks for these videos man. been following these series for a month and I only knew java in the beginning. learned c++ and python just from watching these

bro simple code (just one step) using the builtin std c++
class Solution {
public:
void reverseString(vector<char>& s) {
reverse(s.begin(), s.end());
}
};

Sir it would be a great help if you make separate playlist for easy, medium and different

[FenixFahad]

Nice explanation, Can you please create video for Dynamic Programming tricks and Graph theory algos

[surakarthikeya]

Wt is the difference if we run loop till len /2

[sincereshikha]

why these logics don't click in our mind, we just look for solution
any suggestion?

Wait for some reason I thought it has to be recursive algorithm.
