Repeated square root operations in a given range of numbers












0












$begingroup$


I was curious to find the solution for the question



'Given a range of numbers, return the maximum no of repeated squares root operations within that range'.



For instance, given the range of numbers are (2,20), the perfect squares are [4,9,16] within that range. Now the maximum no of square root operations is 2. Reason behind



 sqrt(16) -> sqrt(4) -> 2. 


I have come with a solution, however, it takes a lot of time to return the results. If you can provide a better version of this code, please let me know.



import math
# For each perfect square, calculate the depth of square root operations
# applied against it.
def square(n):
if n == 2 or n == 1:
return 0
sol = (int(n**0.5))**2
if sol != n : return 0
return 1 + square(int(n**0.5))


A = int(input())
B = int(input())

# Returns the perfect squares within that range
squares = [x for x in range(A,B) if (int(x**0.5))**2 == x]

print(max([square(i) for i in squares]))

    The code doesn't solve the stated problem. It is not asking how many perfect squares are in the range. It asks how many times a square root operation can be iteratively applied starting from some number.
