Expert Solution
Step 1
Time complexity is depends on the number of loops and how many times each loop is executing. In the given code, it contains 2 while loop.
The outer while loop executes n times and the inner while loop executes log n + log (n-1)+ log (n-2) +----+ log 3+ log 2
=log (n*(n-1)*(n-2)*----*2)
=log n!
