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.

answer; the above statement is (true);

we can all learn from our past mistakes because we all have different ways of learning different types of techniques. my way may or may not another classmate remember and have the repetition to acknowledge such standard. such as remembering acronyms. using abbreviations to us remember keep things in order in our memory. this us figure out what comes next in the sequence. if so, what we have is a sentence of just letters all in caps. we either know the meaning or have no idea what it stands for. most of the time we know the meaning and context. but most of us who don't know, should learn by having a quick glance at what needs to be remembered. such as repetition in the memory for acronyms. one way that me, is the fact that i'm always doing math and english assignments. so we have to remember specific meanings such as soapstone for documents, such as citing correctly. or pemdas for doing the equations correctly, even if it's the super long way. this works for everyone. you just have to find what works for you by practicing and repetition daily.
