I'm having a very hard time understanding recursion. Can someone explain to me how this code works. I added some cout statements to try to understand whats going on but it only made me more confuse, I understand from abcdef to fe but after that I'm totally lost.

#include

using namespace std;

string reverseMe(string x){

if (x.length() == 1) {

}

else{

cout

cout

x= reverseMe(x.substr(1,x.length()-1)) + x.at(0);

cout

cout

}

return x;

}

int main() {

string tmp;

cout

getline(cin, tmp);

tmp = reverseMe(tmp);

cout

}
