Given a string of Rs and Gs, design an algorithm to produce a string with Rs in the front and Gs after that. The number of flips from Rs to Gs or otherwise should be minimum. The number of Rs and Gs in the end need not be same as that in the beginning, however the length of the entire string should be the same.

Questions that popped out as I can remember. 1) A cube (1-1-1m) of ice in a room (50C) sitting on a wooden table. the ice is 1m away from the walls around it's 4 sides, except for 1 side is 30cm away. You're given 2 insulating blankets (1m by 1m) that can be used to cover the ice block. The goal is to keep the ice in solid form as long as possible. Where would you put the blankets? 2) 2 rectangular beams, one is Aluminum a by 2b cross-section one is Steel a by b cross-section. If you were to climb a mountain and find these two sticking out on a spot where you need to rest, which one would you latch on to? 3) Interviewee shows a plastic part and asks: How do you think I built this part? What other ways can you think of this part could have been done?
