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 Python (3.4.3) (judge verdict: Accepted)

n = int(input())
num =[]
for i in range(3):
  num.append(int(n%10))
  n /= 10
if(num[0] == 1):
  num[0] = 9
elif(num[0] == 9):
  num[0] = 1
if(num[1] == 1):
  num[1] = 9
elif(num[1] == 9):
  num[1] = 1
if(num[2] == 1):
  num[2] = 9
elif(num[2] == 9):
  num[2] = 1
print(num[0]+num[1]*10+num[2]*100)
