Problem 2

My favourite digit

Simply speaking, you need to know how to handle your numbers well. Given an integer, what is the largest digit present in that number?

The input file **DATA2.txt** will contain 5 lines, integers 0 <= N <= 1,000,000.

The output file **OUT2.txt** will contain 5 lines, each being a single integer 0 <= n <= 9 -- the largest digit present in the corresponding input number.

Sample Input:

1 10 102 1025 9999

Sample Output:

1 1 2 5 9
