This is what interview preparation is doing to me.

Yesterday, I was listening to a song called Yesterday
Now it looks as though it's here to stay
Oh, I believe in recursion

Suddenly, I'm not able to communicate
There's a base case hanging over me
Oh, stack overflow came suddenly

Why it had to crash I don't know it wouldn't say
I wrote something wrong, now I long for yesterday

Yesterday, incrementing i was such an easy code to write
Now I need a place with lots of stack frames
Oh, I believe in redemption

Why it had to crash I don't know it wouldn't say
I wrote something wrong, now I long for yesterday

Yesterday, decrementing j was such an easy game to play
Now I need a place to hide away
Oh, I believe in U.S.A.
Mm mm mm mm mm mm mm...
