Round #633 div2 C (yesterday round):
While Practicing ,I got AC in it ,but i am still not convinced that my solution is correct.
I looked for editorial they said to approach d/f approach as 1 +2 +4 +.... to reach a number . But ,i just simply found the minimum power of 2 which is greater than or equal to our maximum difference. And output that power.
Also to note that in question it was said 2^(x-1) is added to x cost only , but i didn't consider that , i added x for 2^x but still passed TC.
Please Someone tell me ,why i am correct Or give some test case where my solution fails.
