Important Searching & Sorting Topics for GATE CS



Linear search

It is the simplest form of searching where the system starts searching from the beginning till it finds the particular element.

Binary search

The elements in binary search are assumed to be in a specific order, so it involves the following steps:

  • Finding the middle number
  • Searching only left elements, if the searching number is lesser than the middle number.
  • Searching only the right elements, if the searching number is greater than the middle number

Internal sorting

When the number of elements in the sorting process is small, it fits into the memory, it is known as internal sorting.

External sorting

When the number of elements in the sorting process is large, some elements do not fit into the memory, it is known as external sorting.

Bubble sort

Bubble sort is a sorting process that involves reportedly comparing adjacent pairs of elements and checking if they are in the right order. If the order is not right, then the pair is swapped, and the process continues until no swaps are needed.

Insertion sorting

In insertion sorting, an element is removed and inserted in the correct position after every successful iteration in the list as this involves passing through the elements only once. Hence, it is a faster and efficient way of sorting elements.
