The stable_partition( ) algorithm arranges the sequence defined by start and end such that all elements for which the predicate specified by pfn returns true… Read More »

random_shuffle It randomly rearrange elements in range [first, last). The function swaps the value of each element with some other randomly picked element. When provided,… Read More »

Returns true if pred returns false for all the elements in the range [first, last] or if the range is empty, and false otherwise. Syntax… Read More »

C++ offers in its STL library a merge() which is quite useful to merge sort two containers into a single container. It is defined in… Read More »
