Searching and Sorting:

  • Searching Algorithms are designed to check for an element or retrieve an element from any data structure where it is stored
  • Sorting Algorithms are used to rearrange a given array or list of elements according to a comparison operator on the elements. The comparison operator is used to decide the new order of elements in the respective data structure.

Number Series: While a sequence is a list of items arranged in a sequential way following a particular relation, a series is the cumulative sum of a given sequence of terms.

Conversions: This involves questions asking to convert a given number from one number system to an equivalent number in another number system.
