Minimize array length by repeatedly replacing pairs of unequal adjacent array elements by their sum | Function that returns the minimum length of the array after merging unequal adjacent elements.
Stores the first element and its frequency.
Traverse the array.
If all elements are equal.
No merge - pair operations can be performed.
Otherwise.
Given array.
Length of the array.

#Here is code to minimize array length by repeatedly replacing pairs of unequal adjacent array elements by their sum and the other steps required.
 def minLength ( A , N ) :
	elem = A [ 0 ]
	count = 1
	for i in range ( 1 , N ) :
		if ( A [ i ] == elem ) :
			count += 1
		else :
			break
	if ( count == N ) :
		return N
	else :
		return 1
arr = [ 2 , 1 , 3 , 1 ]
N = len ( arr )
print ( minLength ( arr , N ) )
