## What is polyphase sorting explain with example?

A polyphase merge sort is a variation of a bottom-up merge sort that sorts a list using an initial uneven distribution of sub-lists (runs), primarily used for external sorting, and is more efficient than an ordinary merge sort when there are fewer than eight external working files (such as a tape drive or a file on a …

**What is merge sort PPT?**

Merge sort is a sorting technique based on divide and conquer technique. With worst-case time complexity being Ο(n log n), it is one of the most respected algorithms. Merge sort first divides the array into equal halves and then combines them in a sorted manner.

**What is insertion sort explain with example?**

Insertion sort is a simple sorting algorithm that works similar to the way you sort playing cards in your hands. The array is virtually split into a sorted and an unsorted part. Values from the unsorted part are picked and placed at the correct position in the sorted part.

### Which is the best technique for sorting?

The time complexity of Quicksort is O(n log n) in the best case, O(n log n) in the average case, and O(n^2) in the worst case. But because it has the best performance in the average case for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.

**What is external sorting in data structure?**

External sorting is a class of sorting algorithms that can handle massive amounts of data. External sorting is required when the data being sorted do not fit into the main memory of a computing device (usually RAM) and instead they must reside in the slower external memory, usually a disk drive.

**What is multiway merge sort?**

In computer science, k-way merge algorithms or multiway merges are a specific type of sequence merge algorithms that specialize in taking in k sorted lists and merging them into a single sorted list. These merge algorithms generally refer to merge algorithms that take in a number of sorted lists greater than two.

#### What is two way merge sort?

Definition: A k-way merge sort that sorts a data stream using repeated merges. It distributes the input into two streams by repeatedly reading a block of input that fits in memory, a run, sorting it, then writing it to the next stream. It merges runs from the two streams into an output stream.

**What are the steps of insertion sort?**

Insertion Algorithms: Steps on how it works:

- If it is the first element, it is already sorted.
- Pick the next element.
- Compare with all the elements in sorted sub-list.
- Shift all the the elements in sorted sub-list that is greater than the value to be sorted.
- Insert the value.
- Repeat until list is sorted.

**What is the purpose of insertion sort?**

Insertion sort is a simple sorting algorithm that builds the final sorted array (or list) one item at a time. It is much less efficient on large lists than more advanced algorithms such as quicksort, heapsort, or merge sort.

## Which is the fastest sorting technique?

But since it has the upper hand in the average cases for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.

**What is the polyphase circuit theory?**

Vijay Balu Raskar – Electrical Maintenance – Polyphase Circuit Theory – “ Polyphase Circuit” Phase:- Phase of a particular value of an alternating quantity is the fractional part of time period or cycle through which the quantity has advanced from the selected zero position of reference.

**What are the different methods of sorting data?**

• Over a time several methods (or algorithms) are being developed to sort data (s). • Bubble sort, Selection sort, Quick sort, Merge sort, Insertion sort are the few sorting techniques discussed in this chapter. • It is very difficult to select a sorting algorithm over another.

### How to reduce the number of conductors in a polyphase circuit?

Vijay Balu Raskar – Electrical Maintenance – Polyphase Circuit • To reduce the number of conductors, they are inter connected i.e. Star or Wye connection and Delta or Mesh Connection. Star Connection or Wye Connection:- System is balanced and emf’s will be equal in magnitude and displaced 120 from one another.

**What are the different types of sorting in CSE?**
