Best Case Complexity:O(n2) It occurs when the array is already sorted Average Case Complexity:O(n2) It occurs when the elements of the array are in jumbled order (neither ascending nor descending). The time complexity of the selection sort is the same in all cases. At every step, you ...
Implement Java program for selection sort using arrays to sort array elements in ascending order and explains its pros and cons. Selection sort is an in-place comparison sort algorithm. Selection sort has O(n2) time complexity. Selection sort has perform

The selection sort algorithm sorts an array by repeatedly finding the minimum element (considering ascending order) from the unsorted part and putting it at the beginning. The array will have two parts in this process. A subarray which is sorted and other subarrays which is yet to be sorted....
By doing this, the time complexity remains O(N), so it's still slow.19. Is Selection Sort a greedy algorithm?Yes, because it always picks the smallest or largest element in each step.20. How many swaps happen in Selection Sort?
I just sort, though I think it's not important to the complexity. → Reply » relaxgameing20212012 3 months ago, # | ← Rev. 2 0 i dont know what is happening but i am stuck in this weird problem where i am getting correct answer in my local system but after submission i ...
A) Selection sort, B) Merge sort. For each algorithm we will discuss: The main idea of the algorithm. How to implement the algorithm in python. The complexity of the algorithm. Finally, we will compare them experimentally, in terms of time complexity. ...

In Selection sort algorithm , the selection sort algorithm performs passes to find and insert the smallest element into its correct position in an array. Sorting an array with n elements requires (n-1) passes. The time complexity of this algorithm is O(n^2). ...
