An array can be converted into a binary tree. Check whether a given binary tree is skewed binary tree or not? 3) Right Child : Right child of a node at index n lies at (2*n+2). edit Complexity function T(n) — for all problem where tree traversal is … Get hold of all the important Java and Collections concepts with the Fundamentals of Java and Java Collections Course at a student-friendly price and become industry ready. For first case (0—n-1), if (say)father=p; then left_son= (2*p)+1; and right_son= (2*p)+2; For second case (1—n), if (say)father=p; then left_son= (2*p); and right_son= (2*p)+1; where father, left_son and right_son are the values of indices of the array. Example Program To Represent Binary Search Tree Using Arrays (in C): #include . You can visit Binary Trees for the concepts behind binary trees. Well, placement season has started and the tech giant TCS is all set to recruit students from 2015 batch. If you like GeeksforGeeks and would like to contribute, you can also write an article using contribute.geeksforgeeks.org or mail your article to contribute@geeksforgeeks.org. As discussed in the post Binary Trees, the array we will use … To represent tree using an array, the numbering of nodes can start either from 0–(n-1) or 1– n. For first case(0—n-1), if (say)father=p; then left_son=(2*p)+1; and right_son=(2*p)+2;For second case(1—n), if (say)father=p; then left_son=(2*p); and right_son=(2*p)+1; where father, left_son and right_son are the values of indices of the array.
