Can you provide a code to lexicographically smallest permutation of the array possible by at most one swap and the other steps required given the following:
Lexicographically smallest permutation of the array possible by at most one swap | ''Function to print the elements of the array arr[].
'' Traverse the array arr[].
''Function to convert given array to lexicographically smallest permutation possible by swapping at most one pair.
'' Stores the index of the first  element which is not at its  correct position.
'' Checks if any such array  element exists or not.
'' Traverse the given array.
'' If element is found at i.
'' If the first array is  not in correct position.
'' Store the index of  the first elements.
'' Store the index of  the first element.
'' Swap the pairs.
'' Print the array.
''Given array.
''Store the size of the array"

#Here is code to lexicographically smallest permutation of the array possible by at most one swap and the other steps required.
 def printt ( arr , N ) :
	for i in range ( N ) :
		print ( arr [ i ] , end = " ▁ " )
def makeLexicographically ( arr , N ) :
	index = 0
	temp = 0
	check = 0
	condition = 0
	element = 0
	for i in range ( N ) :
		if ( element == arr [ i ] ) :
			check = i
			break
		elif ( arr [ i ] != i + 1 and check == 0 ) :
			index = i
			check = 1
			condition = - 1
			element = i + 1
	if ( condition == - 1 ) :
		temp = arr [ index ]
		arr [ index ] = arr [ check ]
		arr [ check ] = temp
	printt ( arr , N )
arr = [ 1 , 2 , 3 , 4 ]
N = len ( arr )
makeLexicographically ( arr , N )
