- Description
- You will get a lot of 0-1 string(the string only contain 0 and 1).Sort them with the length, put the less one first, if two string has the same length, put the string has less 1 first, if still tied put the one with less string value first.
Compare two string A and B:
From left to right, if the left of i-th character are all the same then compare the i-th character, if A[i] < B[i] then value of A < value of B.
e.g.
compare value 10010111 < 10011000
but compare the number of '1': 10011000 < 10010111
so 10011000 < 10010111
