Algorithms

1. Ways of representing algorithms

   • Pseudocode
     • Loops
       • For...to...next
       • Do...while
     • selection
       • If...Then...Else
       • Case statements
   • Flow charts
     • symbols
       • start/stop
       • Input/Output
       • Decision
       • process

2. An algorithm is set of instructions to solve a specific problem

   • Use pseudocode not real code to represent algorithms
   • Not a program
   • Many algorithms solve one problem
     • faster
     • more effective less memory

3. classic algorithms

   • searching
     • linear
     • binary
   • sorting
     • bubble
     • merge
     • quick
