CPP – Partial Sort Algorithm

We need not sort all elements sometimes. Here are a few simple examples of STL algorithms partial_sort, nth_element, and partition. partial_sort For example, find the 5 biggest ones in 10 random numbers. #include <iostream> #include <vector> #include <cstdlib> #include <ctime> #include <algorithm> using namespace std; int main() { vector<int> values; Read more…

CPP – Ignore Case To Compare String

STL Algorithm std::lexicographical_compare is an algorithm which can be used to compare string lexicographically.We can give our comparing function to make it work without pay attention to capital and small letter. C++ template constexpr bool lexicographical_compare( InputIt1 first1, InputIt1 last1, InputIt2 first2, InputIt2 last2, Compare comp ); Example: C++ #include Read more…

CPP – Unique Copy In STL

std::unique_copy is an algorithm which can be used to copy elements without duplicating objects in adjacent locations. template< class InputIt, class OutputIt > OutputIt uniquecopy( InputIt first, InputIt last, OutputIt dfirst ); Usage example: C++ #include #include #include #include int main() { std::string s1 = “This is a story about Read more…
