  ### Introduction to Algorithms & flow charts
  
  • 1. ALGORITHMS AND FLOWCHARTS
  • 2. ALGORITHMS AND FLOWCHARTS  A typical programming task can be divided into two phases:  Problem solving phase  produce an ordered sequence of steps that describe solution of problem  this sequence of steps is called an algorithm  Implementation phase  implement the program in some programming language
  • 3. Steps in Problem Solving  First produce a general algorithm (one can use pseudocode)  Refine the algorithm successively to get step by step detailed algorithm that is very close to a computer language.  Pseudocode is an artificial and informal language that helps programmers develop algorithms. Pseudocode is very similar to everyday English.
  • 4. The Flowchart A Flowchart  shows logic of an algorithm  emphasizes individual steps and their interconnections  e.g. control flow from one action to the next
  • 5. Flowchart Symbols Basic
  • 6. DECISION STRUCTURES  The expression A>B is a logical expression  it describes a condition we want to test  if A>B is true (if A is greater than B) we take the action on left  print the value of A  if A>B is false (if A is not greater than B) we take the action on right  print the value of B
  • 7. DECISION STRUCTURES is A>B Print BPrint A Y N
  • 8. IF–THEN–ELSE STRUCTURE  The structure is as follows If condition then true alternative else false alternative endif
  • 9. IF–THEN–ELSE STRUCTURE  The algorithm for the flowchart is as follows: If A>B then print A else print B endif is A>B Print BPrint A Y N
  • 10. Relational Operators Relational Operators Operator Description > Greater than < Less than = Equal to ≥ Greater than or equal to ≤ Less than or equal to ≠ Not equal to
  • 11. NESTED IFS  One of the alternatives within an IF–THEN–ELSE statement  may involve further IF–THEN–ELSE statement
explanation: The provided text extract is a set of slides or notes introducing algorithms and flowcharts. It covers topics such as the problem-solving phase, pseudocode, flowchart symbols, decision structures, and nested IF statements. The text does not contain any specific math questions or answers.
distilabel_metadata.content: Evaluate the user given text extract and determine if it contains a math question and optionally and answer to this question.
  
  Output rules:
  
  1. Briefly describe the document and mention if it contains a question or a question and answer.
  2. Finalize the output with: Label: no-question,question,question-and-answer,multiple-question,multiple-question-and-answer
