Ans. 
Various searching methods include BFS, DFS, binary search, and linear search.
• BFS (Breadth-First Search) explores all the vertices at the same level before moving to the next level.

• DFS (Depth-First Search) explores as far as possible along each branch before backtracking.

• Binary search is a divide and conquer algorithm that searches a sorted array by repeatedly dividing the search interval in half.

• Linear search checks ea...read more
