Searching Algorithms

How does a linear search algorithm find a target element in a list?

• It repeatedly divides the list in half until the element is found.

• It checks each element in the list sequentially from beginning to end.

• It starts from the middle and moves outwards.

• It sorts the list first, then checks the middle element.

What type of data arrangement is suitable for a linear search?

• Only numerically sorted data.

• Only alphabetically sorted data.

• Data in any random order.

• Data that is partially sorted.

What is a fundamental requirement for a binary search algorithm to function correctly?

• The data must be unsorted.

• The data must be in a specific order.

• The data must contain only numbers.

• The data must be very small.

How does binary search achieve greater efficiency compared to linear search?

• It checks every element multiple times.

• It sorts the data during the search process.

• It eliminates half of the remaining search space in each step.

• It only works on very small datasets.

Which searching algorithm is generally more efficient for large datasets that are already sorted?

• Linear search

• Binary search

• Both are equally efficient

• Neither is efficient for large datasets
