Hi codeforces, I have a great idea:D
when I read others code in codeforces, I always meet some #define term:
#define pb push_back
#define ppb pop_back
#define FOR(i,a,b) for (int _n(b), i(a); i <= _n; i++)
#define FORD(i,a,b) for(int i=(a),_b=(b);i>=_b;i--)
#define all(c) (c).begin(), (c).end()
Can anyone please make a automatic translator to translate the original simplified code into it's full form? So that people who are not familiar with that can read the code more easily :D
