Hi,
I was trying to practice my coding , and found the following code for splitting string and finally use those to convert to integer and get sum of those numbers.
I found the split string is written is complicated way :
not sure why the" return x == y and x == ' '; " is needed. May be i am not much into stl strings and i need to dig a bit deeper here ?!
thanks

Code:
vector<string> split_string(string input_string) {
string::iterator new_end = unique(input_string.begin(), input_string.end(), [] (const char &x, const char &y) {
return x == y and x == ' ';
});
input_string.erase(new_end, input_string.end());
while (input_string[input_string.length() - 1] == ' ') {
input_string.pop_back();
}
vector<string> splits;
char delimiter = ' ';
size_t i = 0;
size_t pos = input_string.find(delimiter);
while (pos != string::npos) {
splits.push_back(input_string.substr(i, pos - i));
i = pos + 1;
pos = input_string.find(delimiter, i);
}
splits.push_back(input_string.substr(i, min(pos, input_string.length()) - i + 1));
return splits;
}thanks
