Problem Statement

Cat Snuke is learning to write characters.
Today, he practiced writing digits 1 and 9, but he did it the other way around.

You are given a three-digit integer n written by Snuke.
Print the integer obtained by replacing each digit 1 with 9 and each digit 9 with 1 in n.

Constraints

111 \leq n \leq 999

n is an integer consisting of digits 1 and 9.

Input

Input is given from Standard Input in the following format:

n

Output

Print the integer obtained by replacing each occurrence of 1 with 9 and each occurrence of 9 with 1 in n.

Sample Input 1

119

Sample Output 1

991

Replace the 9 in the ones place with 1, the 1 in the tens place with 9 and the 1 in the hundreds place with 9. The answer is 991.

Sample Input 2

999

Sample Output 2

111

Solution in Fortran (gfortran v4.8.4) (judge verdict: Wrong Answer)

program main
implicit None
	character(len =100000)::s
	integer::i,a=1,b=0
    !"0*"が頭だとエラー？
    
	s = "a"
	read (*,"(a)")s
	
	do i = 1,100000
		if(s(i:i) == "0")then
			b = 1
		endif
		if(s(i:i) == "+")then
			if(b == 0)then
				a = a+1
			endif
			b =0
		endif
	enddo
	
	if(b == 1) a = a-1
	
	print"(i0)",a
end program main
