How do I prepare for a code interview?

4 Tips for Preparing for a Coding Interview

1. Build the hard skills. Get in the habit of regularly doing code challenges.
2. Don’t forget the soft skills.
3. Acknowledge multiple solutions.
4. Study your algorithms and data structures.

What are 3 examples of Algorithms?

Here are some more algorithms we can explore on our own to further our knowledge.

• Quicksort.
• Traverse a binary search tree.
• Minimum spanning tree.
• Heapsort.
• Reverse a string in place.

What is the number of comparisons done in the Boyer-Moore algorithm?

The number of comparisons done will be m ∗ (n – m + 1). The Boyer-Moore algorithm is a clever searching technique. Unlike the brute force algorithm, it conveniently skips characters from the string S that do not occur in the pattern P.

What is the worst case time complexity of the KMP algorithm?

It occurs when all the characters of the pattern are same as all the characters of the string. For example, P: ababababa, S:abababababababababababa. In the above algorithms, we saw that the worst case time complexity is O (mn). KMP algorithm solves this problem and reduces the worst case time complexity to O (m+n).

How are string searching algorithms used in everyday life?

In everyday life either knowingly or unknowingly you use string searching algorithms. For instance, every search that you enter into a search engine is treated as a substring and the search engine uses the algorithms of string searching to give you the results.

Is Knuth-Morris-Pratt faster than Boyer-Moore?

I have heard some people saying that the fastest algorithm is Boyer-Moore and some saying that Knuth-Morris-Pratt is actually faster. I have looked up for the complexity on both of them but they mostly look the same O (n+m).
