After seeing the topic, analysis, the factorial of 10 is already very big. The calculation of the end of the number of 0, completely unrealistic, even if the implementation is also very troublesome.
Later, when you think of a number in the factorial of the product has 5 end of the number should be at the end of the result of a 0.
Put it into practice, test a few, no mistakes.

Drazil is playing a math game with Varda.
Let's define for positive an integer x as a product of factorials of its digits. For example,.
First, they choose a decimal number a consisting of n digits that contains at least one digit larger than 1. This number is possibly start with leading zeroes. Then they should find maxim

Abstract: This article provides some simple procedures for calculating factorial, which are also the calculation factorial program written by beginners in many c-language dialects. Although it cannot calculate the big number factorial correctly, it still has many correct ideas. Let's start with an error and start a long and fun journey to explore the path of big
1082-array QueriesPDF (中文版) statisticsforumTime Limit:3 second (s) Memory limit:64 MBGiven an array with n elements, indexed from 1 to n. Now you'll be a given some queries in the form I J, your task was to find the minimum value from index I to J.InputInput starts with an integer T (≤5), denoting the number of test cases.The first line of a case was a blank line. The next line contains the integers N (1≤n≤105), Q (1≤q≤50000). The next line contains N space separated integers forming the array.
Problem DescriptionGiven the parameter n (n is a positive integer), calculate the factorial of n n! The number of "0" is included at the end.For example, 5! =120, which contains the number of "0" at the end of the 1;10! = 3628800, with the number of "0" at the end of the 2;20! = 2432902008176640000, with the number of "0" at the end of which is 4.Calculation FormulaFirst, the calculation formula is given, and the derivation process is given later.So t
