phython Define a function named coin$\_$flip that returns "Heads" or "Tails" according to a random value $1$ or $0.$ Assume the value $1$ represents "Heads" and $0$ represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls function coin$\_$flip$()$ repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than $0.$
