Hello,

I have a query which i faced in Round #570 question D. In that I had used vector of defined size (vector a(n))firstly but it gave me TLE and then after changing the vector to simple array (long long int a[n]) then it passed all the test with the same logic and code just with this change in the code (vector to simple array).

So I want to know why did use of vector gave me TLE?

Thanks in advance.
