Q. How to enter a string "TACK" and return it in reverse order? (After I answered it) What if it is a huge string with too many characters to replace one by one, what would you do? Q. Draw a triangle. Now draw a dot at each of the corners. Each dot represents an ant and each ant can only move in the direction of other ants. (Basically only travel along the sides of the triangle and nowhere else). The ants move at the same speed. What if the probability that the ants never meet?
