Explain in detail about the Ruby arrays
Ruby arrays have many interesting and powerful methods. Besides indexing operations which go well beyond those discussed above, arrays have operations based on set operations (membership, union, intersection, and relative complement), string operations (searching, concatenation, and replacement), stack operations (pop and push), and queue operations (shift and append), as well as more traditional array-based operations (sorting, removing duplicates, reversing, and so forth). Arrays are also tightly bound up with Ruby's iteration mechanism.

What is the best-case number of comparisons performed by mergesort on an input sequence of 2 k distinct numbers?
1. The following is a recursive algorithm to calculate the k -th power of 2. Input k a natural number Output kth power of 2 Algorithem: If k =0then return 1 Else return 2* po
The simplest implementation of the Dijkstra's algorithm stores vertices of set Q into an ordinary linked list or array, and operation Extract-Min(Q) is just a linear search through
In the array implementation of lists, elements are stored into continuous locations. In order to add an element into the list at the end, we can insert it without any problem. But,
Q. How do we represent a max-heap sequentially? Explain by taking a valid example. Ans: A max heap is also called as a descending heap, of size n is an almos
what is string manipulation?
The time required to delete a node x from a doubly linked list having n nodes is O (1)
A queue is a, FIFO (First In First Out) list.
There are three typical ways of recursively traversing a binary tree. In each of these, the left sub-trees & right sub-trees are visited recursively and the distinguishing feature
