nbit-strings, you are asked to find the pair of bit-strings that has the minimum hamming distance.
The first line of the input contains a single integer
n(1 ≤ n ≤ 1000).
nlines contain bit-strings of the same length each on a separate line (1 ≤ || ≤ ).
The program should print the minimum hamming distance of those pairs.
