Data Structures can also be classified ashomogeneousorheterogeneousdata structures depending upon the type of elements in the data structure. In homogeneous data structures, all elements are of the same type, whereas in heterogeneous data structures, the elements may not be of the same type. An ar...

You can use the union-find data structure to check each friend is connected to the other directly or indirectly. You can also determine the two different disconnected subsets. Here, 2 different subsets are {A, B, C} and {D, E}. You have to perform two operations: Union...
Design a data structure that supports addNum to add a number to the stream, and findMedian to return the median of the current numbers seen so far. Also, if the count of numbers is even, return average of two middle elements, return median otherwise. median_stream.cpp Remove the minimum...
