Na kojem principu radi bubble sort?

Najgori slučaj kod bubble sorta je

  • naopako sortiran niz
  • već sortiran niz
  • niz sa približno istim vrijednostima članova
  • niz sa dosta članova sa istom vrijednosti
  • Insertion sort radi tako da se uzme ______ član nesortiranog dijela niza i postavi _________________ u sortiranom dijelu niza.

    Bubble sort ima manju apriornu složenost od insertion sorta.

    Study Notes

    Sorting Algorithms

    • Bubble sort operates on the principle of iterating through an array, comparing adjacent elements and swapping them if they are in the wrong order.
    • The worst-case scenario for bubble sort is when the array is reverse sorted.
    • Insertion sort works by taking an element from the unsorted part of the array and placing it in the correct position in the sorted part of the array.
    • Bubble sort has a lower apriori complexity than insertion sort.
    • The position of elements in the array is crucial for the efficiency of insertion sort.
    • For arrays up to 100,000 elements, insertion sort is better than bubble sort.
    • Among O(n^2) complexity sorts for arrays up to 100,000 elements, the best is insertion sort.

    Merge and Quick Sort

    • Merge sort and quick sort use the divide and conquer principle.
    • The complexity of merge sort is O(nlog2n).
    • The best-case scenario for merge sort is when the array is already sorted.
    • Quick sort's pivot selection is not unique.
    • Merge sort is faster than quick sort due to its O(nlogn) complexity.

    Stacks and Dynamic Data Structures

    • Indirect sorting refers to sorting data that is not physically moved, but rather referenced through pointers.
    • A stack uses the FIFO (First-In-First-Out) principle.
    • A problem with a full stack is solved by allocating more memory or deallocating unused memory.
    • A linear list implemented as a dynamic data structure contains a sequence of nodes.
    • Each node in a linear list contains fields with a value and a reference to the next node.
    • Dynamic linear list means that nodes can be dynamically allocated and deallocated as needed.
