What is the worst-case time complexity for searching an element in a queue?
Step 1: Understand what a queue is. A queue is a data structure that stores elements in a specific order, usually following the First In First Out (FIFO) principle.
Step 2: Know that to search for an element in a queue, you need to look at each element one by one.
Step 3: Realize that in the worst-case scenario, the element you are searching for might be at the very end of the queue or not present at all.
Step 4: Count the number of elements in the queue. If there are 'n' elements, you may have to check all 'n' elements to find the one you are looking for.
Step 5: Conclude that the time it takes to search through all 'n' elements is proportional to 'n', which is expressed as O(n) in Big O notation.
