Given a string formed with 0’s and 1’s. The string is marked with a special character X that represents the middle of the string (for example: 0101011X1101010). Write an algorithm to check whether the string is palindrome or not: (a) If the string is stored as an array (b) If the string is stored as a singlv linked list
Suppose that a list contains the values 20, 44, 48, 55, 62, 66, 74, 88, 93, 99 at index positions 0 through 9. Trace the values of the variables left, right, and midpoint in a binary search of this list for the target value 90. Repeat for the target value 44. [only analytical work is required, no code is necessary; meaning just work the problem out and explain methods. thx :) ]

A fibonacci series is defined as a series where the number at the current index, is the value of the summation of the index preceding it (index -1) and (index-2). Essentially, for a list fibonacci_numbers which is the fibonacci numbers series, fibonacci_numbers[i] = fibonacci_numbers[i-1] + fibonacci_numbers[i-2] The fibonacci series always begins with 0, and then a 1 follows. So an example for fibonacci series up to the first 7 values would be - 0, 1, 1, 2, 3, 5, 8, 13 Complete the fibonacci(n) function, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1. Ex: If the input is: 7 the output is: fibonacci(7) is 13 Important Note Use recursion and DO NOT use any loops. Review the Week 9 class recording to see a variation of this solution. def fibonacci(n): if (n < 0 ): return -1 else: return n fibonacci_numbers = (fibonacci[n - 1] + fibonacci[n - 2]) return fibonacci_numbers(n) # TODO: Write…
Computer Science please solve this problem as soon as possible Write a function to insert the element into the linked list the given number X. E.g., for a given set of integers, [2, 4, 12, 6, 5, 3], the linked list is 2->4->12->6->5->3. For a given number, (X=15), the count will be 11 that are (2,4), (2,12), (2,6), (2,5), (2,3), (4,6), (4,5), (4,3), (6,5), (6,3), (5,3).
Given a list of ‘n’ distinct elements, the task is to find all elements in the list which have at-least two greater elements than themselves. Maintain two separate list, one holding all such greater elements and the other list containing the rest of the elements in the same order. If the number of elements in the input list is less than or equal to 2 then the first list should contain ‘0’ and second list should contain all the input elements in the list.
Computer Science you are given a string X of length n and another string Y of length m ≤n. Say,the indexes p1, p2, p3, p4 and q1, q2, q3, q4 form two sub-sequences, i.e., 0 ≤ p1 < p2 < p3 < p4 < nand 0 ≤q1 < q2 < q3 < q4 < n; then, they are non-overlapping if p4 < q1.The task is to count the maximum number of non-overlapping sub-sequences of X that are thesame as Y . Thus, if X = GAXTYAWBGTAUGBTABGRGTAXB and Y = GTAB, then the answer is3 as shown by the red fonts. We cannot select the underlined GTAB as it overlaps with a red GTAB(i.e., among overlapping sub-sequences, you can select only one of them).Describe an O(m + n) time algorithm to obtain the count. Write a pseudo-code.
Let L={x1,x2,…,xn} be a list of n elements. Let us search for a key K in the list L. If the key is presented in the list L at index(or position) j then partition the list L into disjoint lists L1 and L2 such that L1={x[i]:x[i]εL such that i≤j} and L2={x[i]:x[i]εL such that i>j}. If the key is not present in the list output is “no”. Write an algorithm (using single linked list) and subsequent C program for your algorithm to compute lists L1 and L2 for the given list L and key K. Note: Don’t use any inbuilt functions in your program. Example1: If L={16, 15, 1, 27, 19, 100, 200,3} and key k= 27 then L1={16, 15,1,27} and L2={19, 100,200, 3}. Example 2: If L={16, 15, 1, 27, 19, 100, 200,3} and key k= 127 then no.
A singly linked list contains n - 1 strings that are binary representations of numbers from the set {0, 1,.…, n – 1} where n is an exact power of 2. However, the string corresponding to one of the numbers is missing. For example, if n = 4, the list will contain any three strings from 00, 01,10 and 11. Note that the strings in the list may not appear in any specific order. Also note that the length of each string is lgn, hence the time to compare two strings in O(lgn). Write an algorithm that generates the missing string in O(n).

Create a stack of boxes which is as tall as possible, but you can only stack a box on top of another box if the dimensions of the 2-D base of the lower box are each strictly larger than those of the 2-D base of the higher box. It is possible to rotate a box so that any side functions as its base. It is also allowable to use multiple instances of the same type of box.
