Odd performance disparity between printf(C) and cout(C++)
I solved problem B (permutation chain) of the last contest, and the same exact program using printf and scanf (stdio.h) went over the time limit by a fair chunk (exceeded the time limit by 2s for a single test),instead when using cout and cin (iostream) it passed all tests in 100ms.
Does anyone have any idea why this is happening?
