Skew Binary When a number is expressed in decimal, thek-th digit represents a multiple of 10k. (Digits are numbered from right to left, where the least significant digit is number 0.) For example, When a number is expressed in binary, thek-th digit represents a multiple of 2k. For exam...
解题思路:upper_bound(arr,arr+num,number) - lower_bound(arr,arr+num,number)这个表达式的结果是算出arr数组中有几个number这样的值 #include<cstdio> #include<algorithm> using namespace std; long long A[4100],B[4100],C[4100],D[4100]; long long temp1[10000000]; int cmp(const void *a,cons...
java谜题--1 解惑1: 大佬你可能会觉得输出为:number:101 But not 执行结果如下: 启示: 不要在常量与变量中出现易混淆的字母,常量全部大写并用下滑线分割,变量采用小驼峰命名法命名。 解惑2 大佬你可能会觉得输出为:true,因为 都是90,所以相等。 But not 执行结果如下: 启示: 对于三元运算...【...

css You are given a square matrix consisting of n rows and n columns. We assume that the rows are numbered from 1 to n from top to bottom and the columns are numbered from 1 to n from left to right. Some cells (n - 1 cells in total) of the the matrix are filled with ones...
The first line of the input contains the number of test cases T. The descriptions of the test cases follow: Each test case starts with an integer n (1 ≤ n ≤ 200000) denoting the length of the sequence. In the next line the n elements of the sequence follow, separated with single...

然后我们设11111111...111 (ordn(10) 个1) mod n = r (可以简单的证明出r=1), 那么 11111...111(n * ordn(10) 个1) mod n = n*r = 0, 所以这样的数存在,而且最长不会超过 n*ordn(10)。 当然这个上限很松,实际上实际得到的长度很小, 证明还在酝酿,希望得到大家的帮助。 暴力求解即可。
