Write a loop that asks the user "do you want to repeat the program or quit? (r/q)" . the loop should repeat until the user has entered an r or q (either uppercase or lowercase).

Suppose you have 9 coins and one of them is heavier than others. other 8 coins weight equally. you are also given a balance. develop and algorithm to determine the heavy coin using only two measurements with the of the balance. clearly write your algorithm in the form of a pseudocode using the similar notation that we have used in the class to represent sorting algorithms
