I was solvingtouristsproblem on kattis and keep on getting WA ,I can't understand what I am doing wrong.Here is a link to mycode.The problem is asking for the sum of all paths between such vertex pair (x,y) where y>x and y%x is zero. ...
This is the leetcode problem from a recent contest:https://leetcode.com/problems/minimum-number-of-seconds-to-make-mountain-height-zero/ For some reason, this solution gives a TLE:https://ideone.com/00tSfJ. I have an alternative solution which passes, my question is why does the above so...
什么时候x为0呢,x是32768的倍数的时候,可以发现x为答案的时候只能是32768本身(不能超过2*32768) 也就是x变为32768的最小操作数 这道题需要仔细发现的隐含条件是32768这个终态,实际上:32768=2^15=1<<15 故两种操作是v+i(加几次),v<<j(乘几次2转换为左移几次) 那么得到的数是:(v+i)<<j 要使其...
