How would you sort the array with very huge length?

How to sort a big array with many repetitions?

1. Create an empty AVL Tree with count as an additional field.
2. Traverse input array and do following for every element ‘arr[i]’ …..a) If arr[i] is not present in tree, then insert it and initialize count as 1.
3. Do Inorder Traversal of tree.

Which sorting algorithm is best when array is sorted?

insertion sort
When the array is almost sorted, insertion sort can be preferred. When order of input is not known, merge sort is preferred as it has worst case time complexity of nlogn and it is stable as well.

Which of sorting algorithm is good for array having less than 50 elements?

Insertion sort or selection sort are both typically faster for small arrays (i.e., fewer than 10-20 elements). A useful optimization in practice for the recursive algorithms is to switch to insertion sort or selection sort for “small enough” subarrays.

Which algorithm can be used to sort n integers in the range 1 to N * N in O n time?

Radix sort
Radix sort is a non-comparative integer sorting algorithm that sorts data with integer keys by grouping keys which share same position and value. So it take O(n) time. This discussion on Following algorithm (s) can be used to sort n integers in the range [1 n3] in O(n) time?

How do you find the largest and smallest number in an unsorted integer array?

Algorithm to find the smallest and largest numbers in an array

1. Input the array elements.
2. Initialize small = large = arr[0]
3. Repeat from i = 2 to n.
4. if(arr[i] > large)
5. large = arr[i]
6. if(arr[i] < small)
7. small = arr[i]
8. Print small and large.

How do you sort an array with duplicates?

Program 1: To Sort an Array Having Duplicate Elements

1. Start.
2. Declare an array.
3. Initialize the array.
4. Call a function that will perform the quick sort.
5. Declare two variables: low and high.
6. Call another function partition in the quicksort function.
7. This partition function will divide the function based on the pivot element.

Which sorting method is the fastest for a nearly sorted list?

Bubble sort is fast, but insertion sort has lower overhead. Shell sort is fast because it is based on insertion sort. Merge sort, heap sort, and quick sort do not adapt to nearly sorted data.

Which sorting method is most suitable for sorting a list which is almost sorted?

Bubble sort would be most suitable for sorting a list which is almost sorted. Bubble sort is a type of sorting. It is used for sorting ‘n’ (number of items) elements. It compares all the elements one by one and sorts them based on their values.

Which of the following is good for sorting array having less than 100 elements?

Which of the following is good for sorting arrays having less than 100 elements? Explanation: The insertion sort is good for sorting small arrays.

Which sorting procedure is slowest?

Discussion Forum

Que.	Out of the following, the slowest sorting procedure is
b.	Heap Sort
c.	Shell Sort
d.	Bubble Sort
	Answer:Bubble Sort

Which of the following algorithm can be used to sort n integers in range?

n numbers in range from 0 to n2 – 1? The idea is to use Radix Sort. Following is standard Radix Sort algorithm. Let there be d digits in input integers.

When sorting an array with N elements the maximum number of elements that RadixSort may put in a bucket is N?

When sorting an array with n elements, the maximum number of elements that RadixSort may put in a bucket is n. RadixSort has a space complexity of O(1). RadixSort can be used to sort an array of strings.

Which is better method 2 or 1 for sorting arrays?

” “; We first sort both the given arrays separately. Then we simply merge two sorted arrays. It is obvious from above time complexities that method 2 is better than method 1. This article is contributed by Sachin Bisht.

How much time does it take to insert a sorted array?

For sorted array, insert takes O (n) time as we may have to move all elements worst case. For sorted doubly linked list, insert takes O (n) time to find position of element to be inserted. Since number of insertion operations is asymptotically higher, unsorted array is preferred.

Is O(n log(n)) sort better for millions or billions of integers?

For million integers O (N Log (N)) sort is probably better but for billion they are probably the same. Does it make sense? If you get a question like this, they are not looking for the answer.

Why unsorted array is preferred over sorted array?

Since number of insertion operations is asymptotically higher, unsorted array is preferred. Consider an array consisting of –ve and +ve numbers. What would be the worst case time complexity of an algorithm to segregate the numbers having same sign altogether i.e all +ve on one side and then all -ve on the other?
