good problems
Can someone help me find the bug in my code for Binary Conversion? I can't seem to find what's wrong with the code. A small counterexample would be appreciated.
Edit: nevermind, generated testcases against a correct solution and found the bug
ig if you take like this s = 0 0 t = 0 0 here for any value of k>=1 the value will be YES, becoz you can swap adjacent ele any no of times. but your code is giving YES only for even k
The last TC was for S1==S2 which you have to consider separately. If S1==S2 then if k is even the always possible else if k is odd then length should bhe greater than 2.e.g. 1001 , 1001 both value of k=3 and k=4 will work.This only case wasted my 15 minutes.Hope it helps :)
Can someone tell me how do you solve LEXMINBIN from yesterday's contest? Thanks
