Which programming language is best for algorithms?

C++Most recent answer C++ is the best language for not only competitive but also using to solve the algorithm and data structure problems . C++ use increases the computational level of thinking in memory , time complexity and data flow level.

What are basic algorithms?

Algorithm is a step-by-step procedure, which defines a set of instructions to be executed in a certain order to get the desired output. Algorithms are generally created independent of underlying languages, i.e. an algorithm can be implemented in more than one programming language.

What is the fastest searching algorithm?

Binary search is faster than linear search except for small arrays. However, the array must be sorted first to be able to apply binary search. There are specialized data structures designed for fast searching, such as hash tables, that can be searched more efficiently than binary search.

What is the fastest algorithm?

QuicksortThe time complexity of Quicksort is O(n log n) in the best case, O(n log n) in the average case, and O(n^2) in the worst case. But because it has the best performance in the average case for most inputs, Quicksort is generally considered the “fastest” sorting algorithm.
