SpletInput The only line of input contains an integer m ( 1 ≤ m ≤ 100 000 ) — the required number of trailing zeroes in factorial. Output First print k — the number of values of n such that the factorial of n ends with m zeroes. Then print these k integers in increasing order. Examples Input Copy 1 Output Copy 5 5 6 7 8 9 Input Copy 5 Output Copy 0 Note Splet27. okt. 2015 · To find number of trailing zeroes you divide n first by 5, then 25, then 125, and so on, and then add these numbers together. For a 1000! you'll get: 1000 // 5 + 1000 // 25 + 1000 // 125 + 1000 // 625 = 200 + 40 + 8 + 1 = 249 . how to keep foxes out of your garden uk https://blahblahcreative.com

Splet其实10也是由5 * 2构成，20是由5 * 4构成，其实末尾含0的数也是由5通过与其他数的乘积构成，所以n！中1个因子5对应一个0. 但n！中有些因数含有多个5因子，例如25含有2个5 … Splet28. apr. 2024 · Here we will see how to calculate the number of trailing 0s for the result of factorial of any number. So if the n = 5, then 5! = 120. There is only one trailing 0. For 20! it will be 4 zeros as 20! = 2432902008176640000. The easiest approach is just calculating the factorial and count the 0s. But this approach fails for a large value of n.

Splet04. sep. 2024 · Trailing zeroes are as the name points zeroes in the end of the number. So 10 has 1 trailing zero. And because this is a question regarding base10 numbers, this is how you can represent any number with trailing zero - number0 = number x 10. And because 10 is actually 2 x 5 you need 2s and 5s.
