Given any integer 0 ≤ n ≤ 10000 not divisibleby 2 or 5, some multiple of n is a number whichin decimal notation is a sequence of 1’s. Howmany digits are in the smallest such a multipleof n?InputA file of integers at one integer per line.OutputEach out…
#include <iostream>#include <cstdio>#include <cmath> int main(){ int num; while (scanf_s("%d",&num) != EOF) { int cnt = 2; long long testNum = 11; while (true) { if (testNum%num == 0) { break; } testNum = testNum * 10 + 1;…
题目链接:uva 10127 - Ones 题目大意:给出n,问说者少要多少为1才干够整除n. 解题思路:等于是高精度取模,直到余数为0为止. #include <cstdio> #include <cstring> int main () { int n; while (scanf("%d", &n) == 1) { int ans = 1, c = 1; while (c) { c = (c * 10 + 1) % n; ans++; } print…
Description You, as a member of a development team for a new spell checking program, are to write a module that will check the correctness of given words using a known dictionary of all correct words in all their forms. If the word is absent in the d…
Description Standard web browsers contain features to move backward and forward among the pages recently visited. One way to implement these features is to use two stacks to keep track of the pages that can be reached by moving backward and forward.…
Eugeny has array a = a1, a2, ..., an, consisting of n integers. Each integer ai equals to -1, or to 1. Also, he has m queries: Query number i is given as a pair of integers li, ri (1 ≤ li ≤ ri ≤ n). The response to the query will be integer 1, if the…
