Explain the Arrays in Ruby
Ruby arrays are dynamic arrays which expand automatically whenever a value is stored in a location beyond current end of the array. To the programmer, it's as if arrays are unbounded and as many locations as are needed are available. Locations not assigned a value in an expanded array are initialized to nil by default. Ruby also has an interesting indexing mechanism for arrays. Array indices begin at 0 so, for instance, a[13] is the value in the 14th position of the array. Negative numbers are indices of elements counting from current end of the array, so a[-1] is the last element, a[-2] is the second to last element, and so forth. Array references which use an out-of-bound index return nil. These features combine to make it difficult to write an array reference which causes an indexing error. This is apparently a great convenience to the programmer however actually it's not since it makes it so hard to find bugs: many unintended and erroneous array references are legal.
Merge sort is a sorting algorithm which uses the basic idea of divide and conquers. This algorithm initially divides the array into two halves, sorts them separately and then merge
Write the algorithm for compound interest
In this project you will write a program to produce a discrete time simulation of a queue as shown in Fig. 1. Time is slotted on the input and the output. Each input packet follows
how do you declare char text[80]
nested for loop for (i = 0; i for (j = 0; j sequence of statements } } Here, we observe that, the outer loop executes n times. Every time the outer loop execute
Q. Make a BST for the given sequence of numbers. 45,32,90,34,68,72,15,24,30,66,11,50,10 Traverse the BST formed in Pre- order, Inorder and Postorder.
Let a be a well-formed formula. Let c be the number of binary logical operators in a. (Recall that ?, ?, ?, and ? are the binary logical operators). Let s be the number of proposit
Link list representation of a circular queue is more efficient as it employs space more competently, of course with the added cost of storing the pointers. Program 7 gives the link
how to write an algorithm for unions & intersection of two linklists?
What is quick sort? Quick sort is a sorting algorithm that uses the idea if split and conquer. This algorithm chooses an element called as pivot element; search its position in
