Can I use STL in Google interview?

Can you use STL in coding interviews?

Yes, absolutely. Much more so than in, say, student code, because “industry” programmers are far more likely to know how to use the STL*. The STL is awesome. The STL is generally the best implementation available for the data structures it provides.

Is it good to use STL?

STL is well tested and reliable but it is not the fastest solution. Some of the containers allocate a lot of small memory blocks rather than one big block. If you really have a speed problem then you may consider making your own fixed-size list. But for many purposes STL is the standard solution.

Is AlgoExpert enough for Google interview?

Overall, if you enjoy video explanations of specific questions, AlgoExpert is probably the better choice. But if you want a more holistic approach to solving problems using patterns, Grokking the Coding Interview is the better option.

Can I use priority queue in interview?

Is C++ STL important?

C++ STL provides a range of data structures that are very useful in various scenarios. A lot of data structures are based on real-life applications. It is a library of container classes, algorithms, and iterators.

For which STL We can insert remove data from anywhere?

What is a List in STL? List is a data structure that allows constant time insertion and deletion anywhere in sequence. Lists are implemented as doubly linked lists. Lists allow non-contiguous memory allocation.

How long does algo expert take?

Software Engineer

AlgoExpert got me from zero to ready in 6 weeks. While I bought other prep material, AlgoExpert was easily the best one because of its problem curation, whiteboard videos, optimized solutions, and edge-case testing.

What is priority queue explain with example?

A priority queue is a special type of queue in which each element is associated with a priority value. And, elements are served on the basis of their priority. That is, higher priority elements are served first. However, if elements with the same priority occur, they are served according to their order in the queue.
