Till now, the questions were easily solvable. Here comes a tougher one. I have to accept, this one took a fair amount of time for me to solve. So don’t you easily give up trying. This can be easily solved with a program of size 28 or 26 but we have a constraint of program size being 13. I started pulling my hair when I have a program of size 14 and at last when I found how to rephrase it to make it 13, I felt the joy of conquering the world.
