Ask S (n) = A+aa+aaa+aaaa+...+aa. The value of a, where a is a number, and N is the number of bits of a, for example: 2+22+222+2222+22222 (at this time n=5), N and a are all input from the keyboard.#include int main (){int n;int A;int sum = 0;int k = 0;int temp = 1;scanf ("%

Enter a positive integer n, return a minimum positive integer m (m at least 2 digits), so that M's product equals n, such as input 36, output 49, input 100, output 455, for some n does not exist such m, please return-1. package hope20141002_01; Import java.util.*; public class Jingdong {public static void Main (string[] args) { //TODO auto-generated method

Lucas theorem: N is written in P-ary A[n]a[n-1]a[n-2]...a[0], and M is written in P-b[n]b[n-1]b[n-2]...b[0], then C (n,m) and C (A[

Give you a list of the length of N. N is big, but you don't know how big N is. Your task is to randomly remove k elements from these n elements. You can only traverse this list once. Your algorithm must ensure that the extracted elements happen to have K, and that they are completely random (with equal probability of o

When writing poems or programs, we often have to deal with Euclid's algorithms. However, there is no reason why Euclid's algorithms are effective and efficient, and some extreme (well, allow me to use this strong personal emotional word) computer scientists believe that unless the correctness of the program is mathematically completely strictly confirmed, otherwise we can not think that the program is correct. Since the existence is reasonable, so I will explain in detail the Euclidean algorithm
