1028-trailing Zeroes (I)PDF (中文版) statisticsforumTime Limit:2 second (s) Memory limit:32 MBWe know what's a base of a number is and what's the properties are. For example, we have the decimal number system, where the base is and we use the symbols-{0, 1, 2, 3, 4, 5, 6, 7, 8, 9}. Different bases we use different symbols. For example in binary number system, we use only 0 and 1. Now the This problem is given an integer. You can convert it to any of base

Leetcode-172-factorial Trailing Zeroes

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 min

[Leetcode] Factorial Trailing Zeros

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 l
