http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemId=1405 要求找出4位数所有10进制.12进制.16进制他们各位数字之和相等. #include<cstdio> int getsum(int n,int k) { int sum=0; while(n) { sum+=n%k; n/=k; } return sum; } int main() { int n=1000; while(n<10000) { int sum1…

水题,输出的时候注意下 #include <stdio.h> #include <math.h> int main() { int d; scanf("%d",&d); while(d--) { ]; ; scanf("%d",&n); ) { binary[i++]=n%; n/=; } ; ;j<i;j++) { if(binary[j]) { printf("%d",j); ) printf(&…

属于水题,主要是涉及到回文问题. 这里标注下进制转换的方法: while(n) { p[i]=n%basis; n/=basis; } 见代码: #include <stdio.h> int revert(int n,int base) { int p[20]; int i=0; while(n) { p[i++]=n%base; n/=base; } int ispar=1; for(int j=0,k=i-1;j<k;j++,k--) { if(p[j]!=p[k]) { ispar…

[redundant binary - 冗余二进制]:由0,1,2构成的二进制形式,基数还是2. 现给你一十进制数n,问其可转化成多少种冗余二进制形式. 首先要想到:2x = 2*2x-1 也就是说 10 <=> 02:20 <=> 12: 10000 -> 10000 -> 02000 -> 01200 -> 01120 -> 01112 从上面可以看出,第一位的1保持不变时,有1种冗余二进制形式:第一位的1变为0时,其后有多少个0存在,就有多少种冗…

We have a sorted set of digits D, a non-empty subset of {'1','2','3','4','5','6','7','8','9'}.  (Note that '0' is not included.) Now, we write numbers using these digits, using each digit as many times as we want.  For example, if D = {'1','3','5'},…
