Title Description:F: Factorial DivisionInput two integer n,m output n!/m!Is it very simple? Now we turn the problem in the back, enter k=n!/m! Find such an integer two tuples (n,m)Because the answer is not unique, n should be as small as possible.Input:K (1OutputOutput N and m, no solution output "impossible"Sample Example1201210Case 1:5 1Case 2:impossibleCase 3:7 4Solution: This problem can not be done with multiplication is sure, but how to do it in

Factorial Trailing ZeroesGiven an integer n, return the number of trailing zeroes in N!.Note: Your solution should is in logarithmic time complexity.Beg n! , the number of consecutive 0 in the end.For example 10!=10*9*8*7*6*5*4*3*2*1 so the number of the end 0 is 2Because, n! can be written as the product of factorization,n!=2x~ y z* ..., 2*5=10, so the number of the end 0 equals min (x,z), That is, the minimum value of the number of 2 and 5. The numb

Test instructions: To find the factorial of a number n, the number of the 1th is not the number of 0.Train of thought: [1,n] Multiply each, appear suffix 0 to filter out, for example 12300 becomes 123, continue to count down. To solve the problem of long long, the remaining number of mods, filter out the previous too large part, because the calculation is useless. How much should this mod be? 1 billion on the line.1#include 2 #defineLL Long Long3 usin

Well, to compute the number of trailing zeros, we need to first think clear on what would generate a trailing 0 ? Obviously, a number multiplied by would has 10 a trailing 0 added to it. So we are need to find out how many's would appear in the expression of the 10 factorial. Since 10 = 2 * 5 and there is a bunch more 2 ' s (each even number would contribute at least one 2 ), we only need to count The number of 5 ' s. Now let's see what numbers'll con
