Imagine that you have a list of all the genders (as single characters) of the students in your class, in order of their last name. The list will look something like “MFFMMMFFMFMMFFFM” where “M” is Male and “F” is Female. Write a function (below) percentageGenders(string) to accept a string that represents the genders. You are to count all of the “M”’s and “F”’s in the string, and print out the ratio (as a decimal) of the each gender. For example, if the input string were “MFFF,” then the function should print something like “There are 0.25 Males, 0.75 Females” (Hint: Better multiply something by 1.0 to make sure that you get floats not integers.)
