If N=4 then S=100 Here 100 is smallest integral multiple of 4 whose representation consist of only 0and/or 1 digits.. Privacy Policy. After a cut, rod gets divided into two smaller sub-rods. push(x) -- Push element x onto stack. '*' Matches zero or more of the preceding element. Given a number N, find the smallest "zero-one" number S that is a multiple of N. A "zero-one" number consists of the digits 0 and/or 1. Log in to your account.
