Prep Problem - 13 In this problem, you should write one function named cont characters. This function should accept three parameter variables. You Consume that all three will be strings. You can assume that the first will be a string with zero to many characters, and the second two will both be single-character strings. The function should count how many times the second and third parameters (characters) appear within the first parameter string. Several examples are shown below. . For the three parameters one fish two and the function should print out: and to reared 4 times in the string one fish two Fish . For the three parameters "the deep blue and the function should print out: "e" and "B" appeared 6 times in the string 'the deep blue sea You may call the functions in your code in order to test. However, you should remove all calls to the function before you submit to gradescope. The gradescope tests will call the functions to test them. Name the program prepi). Make sure that gradescope gives you the points for passing the test case
