I tried many times and I got TLE7, on code with cin cout, and the visual studio compiler. BUT with this input only 5 million numbers. It should not give TLE (I used ios and tie), which is more strange in g++, ABSOLUTELY the same code gives AC, with a time of 0.187, the code is MORE THAN 5 TIMES FASTER! I understand that g++ and visual differ a lot in terms of compiler settings, but to have such a big difference, I'm just shocked. I am very interested to find out why this is happening. Usually visual is faster, it is very interesting to find out which settings and in which cases make the compiler faster.
