The reason is pretty straightforward. It demands a lot of code to achieve the desired output. The standard template library, or STL, can help you solve this conundrum.
Considering the amount of time and effort consumed while writing code for functions like sorting and searching, STL can help you perform all these operations with just a single line of code. This library can be immensely useful for problem-solving and technical interview preparation. It includes some prominent template classes for common data structures like vectors, stacks, queues, and some handy algorithmic functions like binary search to make programming easier.
Let's take a look at the algorithms and containers in greater depth, as those are the most commonly used components of the STL. Some of the algorithms included are binary search, sorting, and reverse, which are extremely useful. The syntax is as follows:. The sort function helps you sort all the elements inside the specified data structure in ascending order.
This function takes two parameters: the starting iterator and the ending iterator.

Algorithm Interview Questions Question Python Interview Questions Question DevOps Interview Questions Question In particular: It is safest to assume that insert applied to a deque or a vector will invalidate any iterators or references to elements of the deque or vector.
On the other hand, insert applied to any of the other first-class containers list, map, multimap, set, multiset does not invalidate any of the iterators or references to elements of the container, and deletions from these containers invalidate only iterators or references to the elements deleted.
Remember that if you are using the STL for a given purpose in a situation that requires as a minimal requirement that a certain kind of iterator be used, a more powerful iterator may also be used in that situation Remember that if you have the choice between using an STL algorithm and using an STL container class method to accomplish the same purpose, you should prefer the class method.
Know that any container that is the target of an algorithm must be large enough to hold all elements it will receive, since it will not automatically be increased in size.

Maps store elements in a key-value pair. Each value is mapped with a key unique element. Multimaps function the same way as Maps, but the only difference is that in Multimaps, redundant key values are allowed i. As you can see in the above example, the first two key:value pairs have the same key.
The items are inserted from the rear i. In priority queue , the elements are placed in decreasing order of their values and the first element represents the largest of all the inserted elements. The items are inserted at one end of the stack and an item is deleted from the same end of the stack.
Unordered Associative Containers provides sorted and unordered data structures that can be used for efficient searching operations. Standard Template Library provides us with different generic algorithms. These algorithms contain built in generic functions which can be directly accessed in the program.
The Algorithm and its functions can be accessed with the help of Iterators only. Standard Template Library provides built-in sort method to sort the elements in a particular data structure. Iterators are basically used to point or refer to a particular memory location of the element.
