8 30607A helicopter drops two trains, each on a parachute, onto a straight infinite railway line. There is an undefined distance between the two trains. Each faces the same direction, and upon landing, the parachute attached to each train falls to the ground next to the train and detaches. Each train has a microchip that controls its motion. The chips are identical. There is no way for the trains to know where they are. You need to write the code in the chip to make the trains bump into each other. Each line of code takes a single clock cycle to execute. You can use the following commands (and only these); MF - moves the train forward MB - moves the train backward IF (P) - conditional that's satisfied if the train is next to a parachute. There is no "then" to this IF statement. GOTO

7 28961On the shelf you have 10 identical bottles of identical pills (let?s say there?s a hundred pills in each bottle). However, one of those 10 bottles contains cheap knockoff pills. The only way to differentiate fake pills from real pills is the weight - while real pills weigh 1 g each, the knockoff pills are only 0.9 g. You have one scale that shows the exact weight (down to the mg) of whatever is weighed. How can you tell which bottle contains fake pills with just 1 weighing?
