Don't be mad, take it as experience for later contests.
(Yesterday I used the wrong datatype for problem B, submitted and locked the problem immediately without optimizing the code. I was so careless and got TLE on test 9. After finished the contest, I just changed a few lines of code and it was Accepted. What a pity!)
Join the #define int long long cult! Everyone hates us, and they got a point, but this kind of mistake won't ever happen to you again
I think that #define long long long cult is better.
A good way to avoid these mistakes is to do a mental estimation of the upper bound of the absolute value before assigning datatypes. For example, if there's an array with $$$\le 2 \cdot 10^5$$$ elements between $$$-10^9$$$ and $$$10^9$$$, any subset sum of this array will be between $$$\pm 2 \cdot 10^{14}$$$, which clearly needs a 64-bit integer type. I try to be as specific about the bounds as possible, and it helps me verify my implementation as well, so I'd recommend others to do this too.
Me too!
