Program to check whether a number is Proth number or not | Utility function to Check power of two.
Function to check if the Given number is Proth number or not.
check if k divides n or not.
Check if n / k is power of 2 or not.
update k to next odd number.
If we reach here means there exists no value of K Such that k is odd number and n / k is a power of 2 greater than k.
Get n.
Check n for Proth Number"
How can the above be solved in Python?
