2.1

1. 2.1.1 computational thinking

   • decomposition
     • beaking complex problems to smaller more managable ones
   • algrithmic thinking
     • a logical way to get from a problem to a solotion
   • abstraction
     • picking out the important parts of infomation from the problem ignoring the spesific detailes that don't matter

2. 2.1.2writing algrithoms

   • written using pseudocode
     • not programing langwige
     • follows simalar structure
     • shows an algrithoms steps without wowring about the finer detailes
     • quick to write
     • easily converted into any program langwige
     • diffrent ways to wright
   • flowcharts
     • deceition
     • input / output
     • processes
     • subprograms
     • arrow
     • start / stop

3. search algrithoms

   • binary search
   • linear search
   • bubble sort
   • merge sort
     • advanteges
       • more efishent
       • quiker
       • constant running time
     • disadvantages
       • gose threw all of the list even when it is compleated
       • uses more memory
