A module Parity() takes a string as a parameter. The parameter has the identifier BitString and it represents a binary value. The module will concatenate a single character to the end of BitString by applying one of the two rules: : '0' if Bitstring contains an even number of 1s : '1' if Bitstring contains an odd number of 1s. The modified value of BitString is then returned. For example: Parameter String returned Explanation "0010010110" "00100101100" there are an even number of 1s in the string passed to Parity() so a '0' is concatenated to the end of BitString "101010" "1010101" there are an odd number of 1s in the string passed to Parity() so a '1' is concatenated to the end of BitString Write pseudocode for the module Parity() Assume the parameter BitString can only contain the characters '0' and '1'
