Top 10 algorithms in Interview Questions

In this post “Top 10 coding problems of important topics with their solutions ” are written. If you are preparing for a coding interview, going through these problems is a must.

The memory models that underlie programming languages

Every modern programming environment handles all six of these memory models to some extent, which is one reason our systems are so complicated and hard to understand.

Computers communicate to reach a goal. For instance, you contact Youtube to see cat videos, Youtube responds to gain advertising revenue.

Why Recursive Data Structures?

In this essay, we are going to look at recursive algorithms, and how sometimes, we can organize an algorithm so that it resembles the data structure it manipulates, and organize a data structure so that it resembles the algorithms that manipulate it.

I Wrote a Faster Sorting Algorithm

These days it’s a pretty bold claim if you say that you invented a sorting algorithm that’s 30% faster than state of the art. Unfortunately I have to make a far bolder claim: I wrote a sorting algorithm that’s twice as fast as std::sort for many inputs. And except when I specifically construct cases that hit my worst case, it is never slower than std::sort. (and even when I hit those worst cases, I detect them and automatically fall back to std::sort)
