Write me a code to length of the Smallest Subarray that must be removed in order to Maximise the GCD and the other steps required given the following:
Length of the Smallest Subarray that must be removed in order to Maximise the GCD | Function to find the length of the smallest subarray that must be removed in order to maximise the GCD.
Store the maximum possible GCD of the resulting subarray.
Two pointers initially pointing to the first and last element respectively.
Moving the left pointer to the right if the elements are divisible by the maximum GCD.
Moving the right pointer to the left if the elements are divisible by the maximum GCD.
Return the length of the subarray.
Driver code"
How can the above be solved in Python?
