Revision Points

Standard Algorithms

Make sure you can describe and understand the following algorithms by using: words; pseudocode; flowcharts; structure charts; trace tables; running examples by hand; describing pros & cons in different applications; describing efficiency using big-O notation

• Printing an array using a for loop and array indices
• Populating an array with user input / random numbers
• Summing a numeric array / joining an array of Strings
• Swapping, Inserting, and Deleting Elements
• Searching arrays for maximum and minimum values
• Linear search & Binary search
• Bubble sort & Selection sort & Insertion sort
• Processing strings (extracting, inserting, deleting)

You should also be able to tweak these algorithms for particular applications and and analyse given algorithms to find errors or inefficiencies.
