$29\mathrm{.}8$ LAB: Consecutive heads

Given main$()$ and GVCoin class, complete function consecutive$\_$heads$()$ that counts and returns the number of flips taken to achieve a desired number of consecutive heads without a tails. Function consecutive$\_$heads$()$ has a GVCoin object and an integer representing the desired number of consecutive heads without a tails as parameters.

Note: For testing purposes, a GVCoin object is created in the main$()$ function using a pseudo$-$random number generator with a fixed seed value. The program uses a seed value of $15$ during development, but when submitted, a different seed value will be used for each test case. Refer to the textbook section on random numbers to learn more about pseudo$-$random numbers.

Ex: If the GVCoin object is created with a seed value of $15$ and the desired number of consecutive heads is $5,$ then the function consecutive$\_$heads$()$ returns $16$ and the program outputs:

Total number of flips for $5$ consecutive heads: $16$import random
