Please write to us at contribute@geeksforgeeks.org to report any issue with the above content. Reservation of a future job is done only if there is no existing reservation within k time frame (after and before) It explains how reservation is being done in Indian Railways . edit acknowledge that you have read and understood our, GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Binary Search Tree | Set 1 (Search and Insertion), A program to check if a binary tree is BST or not, Construct BST from given preorder traversal | Set 1. For every reservation request, insert it only when there is no conflicting reservation. We can use self-balancing binary search trees like AVL, Red-Black, .. to do both operations in O(Log n) time. A normal BST takes O(h) time for insert and delete operations.

How to handle duplicates in Binary Search Tree? This project is dedicated to model existing railway reservation systems that aim at development of Railway Reservation System that facilitates the railway customer to manage their reservations and the railway administrator to modify the backend database in a user-friendly manner. This project is developed in c ++ language . Design a data structure to do reservations of future jobs on a single machine under following constraints. This question is adopted from this MIT lecture. structure of the consistent data ... we have covered the issue of BIM and its integration into a railway project. 3) Time is part of the system. Lowest Common Ancestor in a Binary Search Tree. Hashing cannot be used here as the search is not exact search, but a search within k time frame. While inserting job, do “within k time frame check”.
