Read a single integer from the keyboard. Assume this integer represents the number of times you want to flip a coin (with two sides: "H" and "T" for "heads" and "tails" respectively). Show all possible outcomes of "H" and "T" for flipping the coin this many times. You must use recursion for this problem. You may not use any loops for goto) to solve this. Example 1 (user input is underlined): Coin flips? 1 T H Example 2 (user input is underlined): Coin flips? 2 TT TH HT HH Example 3 (user input is underlined): Coin flips? 3 TTT TTH THT THH HTT HTH HHT HHH
