hello @anmolaggarwal.432

since factorials can exceed the range of all primitive datatype , we cant use them.

so the idea is to use array.

intially the array will hold 1. (indicating 1 factorial)
and then iterate from 2 to n(to compute n!) , multiply this number with the number available in array and update the array.

for example if u have to store 23 in array then store it as

 3  | 2

now let say u have to multily this number 23 with 2 .
so simply iterate this array and multiply by 2 but do take care of carry

6 | 4

for printing simply iterate from right to left
