| |Necessary Materials:1 blank sheet of white paper (DIN A4) | | |Place a scan, an image or a link to your algorithm here. || [[File:introductory_algorithm.pdf|Introductory Algorithm]] |
| 1 ruler (30cm)
| |
| 1 geometry triangle
| |
| 1 pencil
| |
| 1 pen (your favorite color — this is the part where you can use your full artistic freedom)
| |
| Steps to follow:
| |
| Place the sheet of paper in front of you vertically. | |
| Mark the top and bottom edge of the paper with a small
| |
| pencil stroke at centimeter 4, measuring from the left edge.
| |
| Mark the left and right edge of the paper with a small
| |
| pencil stroke at centimeter 4, measuring from the top edge.
| |
| Connect the mark on the top edge, with the mark on the bottom edge, with a straight pencil line.
| |
| Connect the mark on the left edge, with the mark on the right edge, with a straight pencil line.
| |
| Align your ruler with the shorter line.
| |
| Align the zero centimeter mark of your ruler, with the intersection of the shorter and the longer line.
| |
| From 0 to 13cm, mark the shorter line with small pencil strokes at each 5mm step.
| |
| Starting from 0.5cm, label your pencil strokes with the letters of the alphabet from A to Z.
| |
| Align your ruler with the longer line.
| |
| Align the zero centimeter mark of your ruler, with the intersection of the shorter and the longer line.
| |
| From 0 to 13cm, mark the longer line with small pencil strokes at each 5mm step.
| |
| Starting from 0.5cm, label your pencil strokes with the letters of the alphabet from A to Z.
| |
| The structure created so far, will be called coordinate system from now on.
| |
| The ability to work with a coordinate system is assumed.
| |
| Before executing the next step, read the next three steps and the example.
| |
| Use the pen of your favorite color, to write down your first name,
| |
| in block letters, in the square, in the upper-left corner of the paper
| |
| (if you have multiple prenames, choose one).
| |
| Use the pen of your favorite color, to write down your family name,
| |
| in block letters, beneath your first name, so that each letter builds
| |
| a pair with a letter of your first name.
| |
| If one of your names (first name or family name) has less letters than the other, extend the
| |
| shorter name with letters from its beginning, until it matches the length of the longer name.
| |
| Example: BEN becomes BENBE
| |
| FROST FROST
| |
| The extended name will still be referred to as first name or family name in the following steps.
| |
| Find the first letter of your first name, on the horizontal axis of the coordinate system.
| |
| Find the first letter of your family name, on the vertical axis of the coordinate system.
| |
| Use the geometry triangle to mark the position in the coordinate
| |
| system with a small dot (you may draw guide lines with the pencil).
| |
| Label the dot with the number of the current letter-combination.
| |
| Repeat the last 4 steps of the algorithm for each letter-combination of your names successively,
| |
| starting with the first letter-combination and ending with the last letter-combination.
| |
| Connect the numbered dots in ascending order, using the pen of your favorite color.
