Write me a code to minimum index to split array into subarrays with co and the other steps required given the following:
Minimum index to split array into subarrays with co | Function to find the GCD of 2 numbers.
Base Case.
Find the GCD recursively.
Function to find the minimum partition index K s . t . product of both subarrays around that partition are co - prime.
Stores the prefix and suffix array product.
Update the prefix array.
Update the suffix array.
Iterate the given array.
Check if prefix [ k ] and suffix [ k + 1 ] are co - prime.
If no index for partition exists , then return - 1.
Driver Code.
Function call"
How can the above be solved in Python?
