The following code implements Newton's algorithm for finding the square root of a number using repetition: n = 17 # we want the square root of 17 for example # our guess is 4 initially # we want to stop when we are this close g = 4 error = 0.0000000001 while abs(n - (g**2)) > error: g = g - ((g**2 - n)/(2 * g)) # g holds the square root of n at this point Implement this algorithm in a function sqRoot (n), that returns the square root using recursion. Assume that the function will be called with positive numbers only. Note: Your initial guess cannot be zero!
