Can you provide a code to length of longest subarray of length at least 2 with maximum GCD and the other steps required given the following:
Length of longest subarray of length at least 2 with maximum GCD | Function to calculate GCD of two numbers.
Function to find maximum size subarray having maximum GCD.
Base case.
Let the maximum GCD be 1 initially.
Loop through array to find maximum GCD of subarray with size 2.
Traverse the array.
Is a multiple of k , increase cnt.
Else update maximum length with consecutive element divisible by k Set cnt to 0.
Update the maxLength.
Return the maxLength.
Driver Code.
Function call"

#Here is code to length of longest subarray of length at least 2 with maximum GCD and the other steps required.
 def gcd ( a , b ) :
	if b == 0 :
		return a
	return gcd ( b , a % b )
def maxGcdSubarray ( arr , n ) :
	if n == 1 :
		return 0
	k = 1
	for i in range ( 1 , n ) :
		k = max ( k , gcd ( arr [ i ] , arr [ i - 1 ] ) )
	cnt = 0
	maxLength = 0
	for i in range ( n ) :
		if arr [ i ] % k == 0 :
			cnt += 1
		else :
			maxLength = max ( maxLength , cnt )
			cnt = 0
	maxLength = max ( maxLength , cnt )
	return maxLength
arr = [ 18 , 3 , 6 , 9 ]
n = len ( arr )
print ( maxGcdSubarray ( arr , n ) )
