WebIn general, both STL set and map has O (log (N)) complexity for insert, delete, search etc operations. But in some problems, where N<=10^5, O (NlogN) algorithms using set gives TLE, while map gets AC. Can someone please explain how map gives a better runtime than set? Thanks in advance :) stl +14 katukutu 7 years ago WebSearches the container for elements equivalent to val and returns the number of matches.

WebThe std::all_of () function is a STL Algorithm in C++. It can be used to check if all the elements of a sequence satisfies a condition or not. The sequence can be a vector, array, list or any other sequential container. We need to include the header file to use the std::all_of () function. Syntax of std::all_of () Copy to clipboard WebC++11 (1) empty container constructor (default constructor) Constructs an empty container, with no elements.
