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.
1. A string s is said to be periodic with a period α, if s is α k for some k > 2. (Note that α k is the string formed by concatenating k times.) A DNA sequence s is called a tand
What is Assertions Introduction At every point in a program, there are generally constraints on the computational state that should hold for program to be correct. For ins

If quicksort is so quick, why bother with anything else? If bubble sort is so bad, why even mention it? For that matter, why are there so many sorting algorithms? Your mission (sho

What is multiple queue and explain them
Q. Give the algorithm for the selection sort. Describe the behaviours of selection sort when the input given is already sorted.
Linear search is not the most efficient way to search an item within a collection of items. Though, it is extremely simple to implement. Furthermore, if the array elements are arra
