Time and space complexities of various sorting methods?
Bubble sort-O(n*n)-in all cases Insertion sort-O(n*n)-in avg and worst case in best case it is O(logn) Quick Sort-0(nlogn)-in avg n best case and 0(n*n)-in Worst case selection sort-same as bubble Linear search-o(n) Binary Search-o(nlog) Any doubt mail me-jain88visionary@rediffmail.com
What is insertion sorts in worst case time?
Best case for insertion sort is O(n), where the array is already sorted. The worst case, where the array is completely reversed, is O(n*n).

Who is best merge sort or insertion sort?
Merge sort is good for large data sets, while insertion sort is good for small data sets.
What is best and average case of binary search?
Merge sort is O(n log n) for both best case and average case scenarios.
Why comparisons are less in merge sort than insertion sort?
the main reason is: Merge sort is non-adoptive while insertion sort is adoptive the main reason is: Merge sort is non-adoptive while insertion sort is adoptive

Why do you need to sort data before searching?
Sorting data before searching can significantly improve search performance because it enables more efficient search algorithms like binary search to be used. Sorting allows for faster lookup times by reducing the number of comparisons needed to find a specific value in the data set.
What are issues of binary sort?
There's no such thing as a binary sort. You are possibly referring to a binary insertion sort which is based upon binary search. The most efficient binary search makes use of a sorted array. This offers us constant-time random-access to any element. By keeping track of the upper and lower indices of a subset, we can easily calculate the middle element of that subset: middle = (upper - lower) / 2 + lower Given an array A of length n, we can search for a given value as follows: unsigned search (const int* A, const unsigned n, int value) { int lower = 0; int upper = n; while (lower<upper) { int middle = (upper - lower) / 2 + lower; if (value == A[middle]) return middle; else if (value < A[middle]) upper = middle; else lower = middle+1; } return n; } Note that we return the index of the value if found. If not, we return n, which is the index one-past-the-end of the array. We can use the algorithm as follows: unsigned find; const unsigned max = 10; int X[max] = {3, 5, 7, 9, 11, 13, 15, 17, 19, 21}; // sorted array find = search (X, max, 15); // search for value 15 assert (find==6); find = search (X, max, 20); // search for non-existent value assert (find==max); We can modify the binary search algorithm such that we can locate the insertion point for a new value, thus creating a binary insertion sort. First, we locate the insertion point: unsigned find_insert (const int* A, const unsigned n, int value) { int lower = 0; int upper = n; while (lower<upper) { int middle = (upper - lower) / 2 + lower; if (A[middle]>value && (middle==0 A[middle-1]<=value)) return middle; else if (value < A[middle]) upper = middle; else lower = middle+1; } return n; } Note that we're now looking for a value that is greater than our value such that the previous value is less than or equal to our value or there is no previous value. With this algorithm in place, we can now perform the insertion: unsigned insert (int* A, const unsigned n, int value) { unsigned index = find_insert (A, n, value); for (unsigned i=n; i>index; --i) A[i] = A[i-1]; A[index] = value; return index; } Note that, prior to invoking the insertion, you must reserve one or more unused elements at the end of the array (at index n or beyond).

How do you sort a link list?
You copy the list, while using an insertion sort criteria.
Which algorithm is more efficient- insertion sort algorithm or merge sort algorithm?
On average merge sort is more efficient however insertion sort could potentially be faster. As a result it depends how close to reverse order the data is. If it is likely to be mostly sorted, insertion sort is faster, if not, merge sort is faster.
