So I was reading this sumitter's solution on codeforce , here is the link of his/her code https://codeforces.com/contest/1714/submission/166585583
The "for" I asker is in main().I'm wondering what is this "for" syntax called or any keyword for me to look for it because it's different from the for(int i;i < Number;i++)
I have learned.
cltstream::read(T);
for (; T; --T)
