[theory] Stem and leaf

 Stem and leaf theory

Lets start with a definition to stem and leaf plot.

A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit) [1]

Lets take an example to make it more clear. If you have the following table to represent the stems and leafs:

stem	leafs
1	2 3 5 6 7
2	1 1 0
3	0
4	9 8 2

The way we would read this table is:

For the first row:

12  13  15  16  17

The second row

21  21  20

The third row

30

The fourth row

49  48  42

The red numbers are the stems and the blue ones are the leafs. The stems will be the TENS place value where the leafs will be the ONES place value. This piece of information is important because it will help us in the calculation of stems and leafs.

Now that you got an idea about the stems and leafs let go and make a program to calculate it.
