We have collected some solid points that will help you understand the pros and cons of Linear Search in detail.

But first, let’s understand the topic:

## What is Linear Search?

Linear search is a method of searching for a specific element in an array by checking each element one at a time. This method is simple to implement, but it can be slow for large arrays as it requires checking each element. Linear search is also known as a sequential search.

Easy to understand Time-consuming
No special data structure required Not suitable for large data sets
Can be used on unsorted data Not suitable for ordered data
Not affected by data size Not suitable for real-time applications

1. Easy to understand – Linear search is a simple algorithm that is easy to understand and implement, making it a great option for beginners. It works by sequentially checking each element in a list until the desired element is found, making it a straightforward process.
2. No special data structure required – Linear search can be applied to any data structure, making it a versatile option. It doesn’t require any special type of data structure like a balanced tree or a hash table, which can make it simpler to implement.
3. Can be used on unsorted data – Linear search can be used on unsorted data, which can be an advantage in certain situations. This is in contrast to other search algorithms like binary search which require the data to be sorted.
4. No additional memory required – inear search does not require any additional memory to be used, making it a more efficient option in terms of memory usage. This is in contrast to other search algorithms like hash table which require additional memory to store the indexes.
5. Not affected by data size – Linear search is not affected by the size of the data and can be used to search for elements in large lists. This is because the algorithm takes the same amount of time to search for an element regardless of the size of the list.

1. Time-consuming – Linear search can be time-consuming, especially when dealing with large lists. It checks each element one by one, which can take a lot of time when searching for an element in a long list. This makes it less efficient than other search algorithms like binary search.
2. Not suitable for large data sets – Linear search is not as efficient as other search algorithms when dealing with large data sets. It can take a long time to search for an element in a large list, which can be a significant disadvantage when dealing with big data.
3. Not suitable for ordered data – Linear search is not suitable for ordered data. Other search algorithms like binary search are more efficient when searching for an element in ordered data.
4. Not suitable for repetitive task – Linear search can be time-consuming and inefficient when used for repetitive tasks. It’s not suitable for tasks that require multiple searches, as it will take longer to search for the same element multiple times.
5. Not suitable for real-time applications – Linear search is not suitable for real-time applications as it can take a long time to search for an element. This can be a significant disadvantage in applications where a quick response time is required.

That’s it.
