Is selection sort and tournament sort are same?
No. Tournament sort is a variation of heapsort but is based upon a naive selection sort. Selection sort takes O(n) time to find the largest element and requires n passes, and thus has an average complexity of O(n*n). Tournament sort takes O(n) time to build a priority queue and thus reduces the search time to O(log n) for each selection, and therefore has an average complexity of O(n log n), the same as heapsort.
When is quick sort better than selection sort?
Because the quick sort can be used for large lists but selection not. selection sort is used to find the minimum element ,but quick choose element called pivot and move all smaller nums before it & larger after it.
How do you implement selection sort in c with graphics?
Selection sort has the following implementation: // sort an array if integers of length size in ascending order using selection sort algorithm: void selection_sort (int a[], unsigned size) { unsigned i, max; while (size > 1) { max = 0; for (i=1; i!=size; ++i) if (a[i] > a[max]) max = i; swap (a[max], a[--size]); } }
What are the applications of selection sort?
None. Selection sort can only be used on small sets of unsorted data and although it generally performs better than bubble sort, it is unstable and is less efficient than insert sort. This is primarily because insert sort only needs to scan as far back as required to perform an insertion whereas selection sort must scan the entire set to find the lowest value in the set. And although selection sort generally performs fewer writes than insert sort, it cannot perform fewer writes than cycle sort, which is important in applications where write speed greatly exceeds read speed.
What is the number of swaps required to sort n elements using selection sort in worst case?
O(n2)
How many passes would be required in Selection Sort if number of elements are 5?
5 ( 5 - 1 )

What is the best data structure for heap sort?
selection sort
What is the operation of a selection sort?
You sort a selected range of cells.
When is quick sort better than selection sort?

What are the advantages and disadvantages of selection sort?
No

Did exchange method is possible in sorting algorithms in data structures?
yes....exchange checking are: bubble sort, selection sort , quick sort
What is the number of swaps required to sort n elements using selection sort in worst case?
O(n2)
Different types of sorting techniques in c language?
types of sorting in c language are: insertion sort selection sort bubble sort merge sort two way merge sort heap sort quick sort
What is the difference between bubble sort and selection sort in pascal?
The traditional bubble sort moves any number of elements at most one position per iteration, while selection sort moves exactly one element per iteration. Both sorts require an exponential amount of time to produce their results.
