Tally marks are an example of a numeral system with unary encodings. A number n is represented with n tally marks. For example, 4 is represented as the string "| | | |", where each vertical line "|" is a tally. A recursive version of this definition of this encoding is as follows: Base Case: 0 is represented with zero tally marks. Recursive Case: A positive number n is represented with (1 + the number of tally marks in the representation of n-1) tally marks. Write a recursive function to calculate the unary encoding of a non-negative integer. Name the function unary_encoding(n), where n is a non-negative integer (0, 1, 2, …) and make the output a string of "|" characters separated by blank spaces, with no whitespace on the ends.

This program should be a short piece of code that prints all of the positive integers from 1 to 100 as described more fully below. the program may contain multiple methods, and if using an oo language, should be contained within a single class or object. the program should be designed so that it begins execution when invoked through whichever mechanism is most common for the implementation language. â–ş print out all positive integers from 1 to 100, inclusive and in order. â–ş print messages to standard output, matching the sample output below. â–ş in the output, state whether the each integer is 'odd' or 'even' in the output. â–ş if the number is divisible by three, instead of stating that the number is odd or even, state that the number is 'divisible by three'. â–ş if the number is divisible by both two and three, instead of saying that the number is odd, even or divisible by three; state that the number is 'divisible by two and three'. â–ş design the logic of the loop to be as efficient as possible, using the minimal number of operations to perform the required logic. sample output the number '1' is odd. the number '2' is even. the number '3' is divisible by three. the number '6' is divisible by two and three.
