Remove Duplicates From a Vector in C++ Using std::sort and std::uniqueRemoval of duplicate elements from a vector in C++ can be efficiently achieved using the combination of std::sort and std::unique, two powerful functions provided by the C++ Standard Template Library (STL)....

Removing Duplicate Elements from Array We need to remove duplicate elements from array so that each element only appears once (all the values in the array should become unique). Example Input: [1,2,2,3,4,4,4,5,5] Output: [1,2,3,4,5] Explanation The frequency of each element is sh...
This post will discuss how to remove an element from the end of a vector in C++. The solution should effectively reduce the vector size by one.
Example 1: Create New Vector without NA Values Example 2: Remove NA within Function via na.rm Video & Further Resources With that, let’s do this: Creation of Example Data In the two examples of this R tutorial, I’ll use the followingvector: ...
