Kerri takes 3 vitamin pills per day. Each pill has a defined amount of Vitamin C, but the amount actually varies. Let F be the amount of Vitamin C in a Fab pill in mg. Let I be the amount of Vitamin C in an Iab pill in mg. Let H be the amount of Vitamin C in a Hab pill in mg. We will look at F, I and H. F has a mean of μF = 31.4 mg...

Write a recursive Racket function "remove-char" that takes two string parameters, s and c, and evaluates to string s with all occurrences of c removed. The string c is guaranteed to be a length-1 string; in other words a single character string. For example (remove-char "abc" "b") should evaluate to "ac". Here is pseudocode that you could implement.

6.19 LAB: Convert to binary - functionsWrite a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binary. For an integer x, the algorithm is:As long as x is greater than 0 Output x % 2 (remainder is either 0 or 1) x = x / 2Note: The above algorithm outputs the 0's and 1's in reverse order. You will need to write a second function to reverse the string.Ex: If the input is:6the output is:110Your program must define and call the following two functions. The IntegerToReverseBinary function...
