Bubble sort Algorithms
- set out an array of a pack of thirteen cards of the same suit in a straight line (shuffled first)
- Place a finger on a card and another on the card beside it- beginning from the left
- Swap the cards your fingers are on IF the card on the left has higher value than the one on the right.
- If not move up the line
- Repeat the process until the cards are in the correct order.

Binary Codes
Computers use binary codes to transport calculate and translate because computer hardware circuits only have two electrical states on (one) and off (zero). All the letters of the alphabet, numbers and symbols are converted into eight character binary codes as you work with them in Computer software.
Down below a picture of computer binary code translated into the English alphabet.
Pseudo Code
Pseudo is not an actual programming language, Although it does make creating programs easier.It uses short phrases to write code for programs before you actually create it in a specific language.Once you know what the program is about and how it function, you can use it to create small phrases.
Flowchart
The common symbols in a flowchart:
- Terminator: An oval flow chart shape showing the start or end of the process.
- Process: A rectangular flow chart shape showing a normal process flow step.
- Decision: A diamond flow chart shape showing a branch in the process flow.
For example:
