Why in some problems I find myself in the choice of using C or C++ to solve the problem and accept it. for example this code in java https://codeforces.net/contest/433/submission/42722521 Time limit in the last test case test 46 which this test must take less time than which the code pass but when I use the same code in C++ https://codeforces.net/contest/433/submission/42722213 accepted in time ( 186 ms ) and test 46 took ( 15 ms )
