Data Structures Coding Problems

Data structure is a technique of storing, managing, organising and performing operations on the data. The coding problems in Data structures include topics such as Arrays, Linked Lists, Stacks, Trees, heaps, bit manipulation and Dynamic programming.
To crack any technical interview, candidates must be proficient in data structures. To solve these problems, first, one must be clear about the concept, then try to develop the approach while understanding the problem, think of the correct data structure and try writing pseudocode first. Analyse the time, and space complexity of the solution developed, try thinking of any better approaches possible. Optimise your solution if possible, and then write the proper code and add comments. Adding comments proves to be a cherry on the cake in many interviews.
