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: Accepted)

program sunuke

implicit none

integer::    n
integer::    x,y,z

read(*,*) n
x=int(n/100)
n=n-100*x
y=int(n/10)
z=n-10*y


if(x==1) then
  x=9
else if(x==9) then
  x=1
endif
if(y==1) then
  y=9
else if(y==9) then
  y=1
endif
if(z==1) then
  z=9
else if(z==9) then
  z=1
endif

n=100*x+10*y+z

write(*,*) n

end program sunuke
