Splet28. apr. 2024 · Factorial Trailing Zeroes in C++. 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. SpletIn mathematics, trailing zeros are a sequence of 0 in the decimal representation (or more generally, in any positional representation) of a number, after which no other digits follow. …
