Count numbers up to N that cannot be expressed as sum of at least two consecutive positive integers | Function to check if a number can be expressed as a power of 2.
if N is power of two.
Function to count numbers that cannot be expressed as sum of two or more consecutive + ve integers.
Stores the resultant count of integers.
Iterate over the range [ 1 , N ].
Check if i is power of 2.
Increment the count if i is not power of 2.
Print the value of count.
