撸完这题,感觉被掏空. 由于进制可能大的飞起..所以需要开longlong存,答案可以二分得到. 进制很大,导致转换成10进制的时候可能爆long long,在二分的时候,如果溢出了,那么上界=mid-1 #include<iostream> #include<cstring> #include<cmath> #include<algorithm> #include<cstdio> using namespace std; ],t[]; int…

题意: 输入两个数可能包含小写字母,1或者2,进制大小.第三个数为代表第一个数是第四个数进制的,求第二个数等于第一个数时进制的大小,不可能则输出Impossible,第三个数为2代表第二个数是第四个数进制的,求第一个数等于第二个数时进制的大小,不可能则输出Impossible.数字的位数最多是十位. trick: 进制可能很大,所以运算过程中可能会爆long long,不必担心,当成负数处理即可. AAAAAccepted code: #include<bits/stdc++.h> using…
