Count occurrences of a prime number in the prime factorization of every element from the given range | Function to return the count of times p appears in the prime factors of the elements from the range [ l , r ].
To store the required count.
Number of values in the range [ 0 , r ] that are divisible by val.
Number of values in the range [ 0 , l - 1 ] that are divisible by val.
Increment the power of the val.
( a - b ) is the count of numbers in the range [ l , r ] that are divisible by val.
No values that are divisible by val thus exiting from the loop.
