Count of pairs in range [ P , Q ] with numbers as multiple of R and their product lie in range [ P * Q / 4 , P * Q ] | Function to find the number of pairs such that both the elements are in the range [ P , Q ] and the numbers should be multiple of R , and the product of numbers should lie in the range [ P * Q / 4 , P * Q ].
Store multiple of r in range of [ P , Q ].
Itearte in the range [ p , q ].
Vector to store pair of answer.
Iterate through the vector v.
Iterate in the range [ i + 1 , v . size ( ) - 1 ].
If pair follow this condition insert the pair in vector ans.
If no pair satisfy the conditions , pr - 1.
Print the pairs which satisfy the given condition.
Driver Code.
Given Input.
Function Call"
How can the above be solved in Python?

Write me a code to count of pairs in range [ P , Q ] with numbers as multiple of R and their product lie in range [ P * Q / 4 , P * Q ] and the other steps required?
