Solution
This answer passes all the tests
We are going to keep logic in main function only such that we are able to build array as we will be getting data from input.
You shall create a script.py file and paste the below code in it.
1st line: arr = int(input()) This takes input from command line. Please note that input type is going to be in string
format and we have to use int() to convert from string to int
2nd line: a=1 This is to intialize the number.
if __name__ == '__main__':
arr = int(input())
a = 1
for i in range(1,arr+1):
a = a*i
print(a)Top articles in this category:
