Now that you can simulate coin flips, and do it lots of times, lets try to explore the reality of coins a bit further. People generally think that getting a streak of coin flips, where the same side comes up over and over again, is extremely rare. In reality, it happens quite often. Write a function, coin_streak, that takes as input a number which is the streak length, and performs random flips until a streak of that number is achieved. The function should record the total number of flips needed to get a streak.

So, the function should look like the following:

Number of flips needed for streak of 10: 874
