Can you provide a code to smallest subarray with k distinct numbers and the other steps required given the following:
Smallest subarray with k distinct numbers | Prints the minimum range that contains exactly k distinct numbers ..
Consider every element as starting point ..
Find the smallest window starting with arr [ i ] and containing exactly k distinct elements ..
There are less than k distinct elements now , so no need to continue ..
If there was no window with k distinct elements ( k is greater than total distinct elements ).

#Here is code to smallest subarray with k distinct numbers and the other steps required.
 def minRange ( arr , n , k ) :
	l = 0
	r = n
	for i in range ( n ) :
		s = [ ]
		for j in range ( i , n ) :
			s . append ( arr [ j ] )
			if ( len ( s ) == k ) :
				if ( ( j - i ) < ( r - l ) ) :
					r = j
					l = i
				break
		if ( j == n ) :
			break
	if ( l == 0 and r == n ) :
		print ( " Invalid ▁ k " )
	else :
		print ( l , r )
if __name__ == " _ _ main _ _ " :
	arr = [ 1 , 2 , 3 , 4 , 5 ]
	n = len ( arr )
	k = 3
	minRange ( arr , n , k )
