Determine whether an integer is a palindrome. An integer is a palindrome when it reads the same backward as forward. For example, 12321 is a palindrome number.

Follow up: Could you solve it without converting the integer to a string?

Create a class named Palindrome which will contain the main method. All your code goes in the main method.

Sample Input and output:

Example 1:

Input: x = 121

Output: true

Example 2:

Input: x = -121

Output: false

Explanation: From left to right, it reads -121. From right to left, it becomes 121-. Therefore it is not a palindrome

Example 3:

Input: x = 10

Output: false

Explanation: Reads 01 from right to left. Therefore it is not a palindrome.

Example 4:

Input: x = -101

Output: false

Example 5:

Input: x = 3

Output: true

. Write a program for: search(LA,ITEM) in Java

1. Search whether the user's entered item is exist or not in the array if exist perform following

2. Print two right neighbors(item/value) in case no right neighbor print message 'no right neighbor'

3. Print two le neighbors(item/value) in case no le neighbor print message 'no le neighbor

 Write a program for: insert(LA, K, ITEM )

1. K is not out of range

2. Item must be posive integer

3. Check user's entered ITEM at index K is greater or less than in an array at index K, if less than insert it into the array otherwise not perform any operaon, and prints the message 'ITEM’ at index k is greater than user's entered ‘ITEM' 

1. Anagrams!

by CodeChum Admin

Two strings are called anagrams, if they contain the same characters, but the order of the characters may be different.

Given a string consisting of lowercase letters and question marks, s1, and another string consisting of lowercase letters, s2, determine whether these two strings could become anagrams by replacing each ? character in s1 with a letter.

Input

1. First string

Constraints

Contains only lowercase letters and/or question marks

2. Second string

Constraints

Contains only lowercase letters

Output

The first line will contain a message prompt to input the first string.

The second line will contain a message prompt to input the second string.

The last line contains the message "anagram" if the strings could become anagrams by replacing all the ? characters of s1 with letters and "false" otherwise.

Create a GUI application to enter three different numbers in three textboxes. Write a program to find the Factorial of the smallest number and factors of the largest number entered and print the result. Apply condition that the number entered must be positive only

Write a program to create two Threads. 1st Thread printing the table of the number (each after a period of 1 sec) entered by the user and 2nd Thread printing each character of the sentence after a period of 1s. Thread 1 must be executed first completely before starting of thread 2.

You should create two methods for a data structure implementing a Queue as a

circular array. Your data structure should have the class name MyArrayQueue. The

two methods that should be implemented are:

a) Adding element to the queue:

public void enqueue(Object theElement) {…}

[20 marks]

(Functionality: 15, Design: 2, Ease of use: 2, Presentation: 1)

b) Deleting an element from the queue and return the deleted element:

public Object dequeue() {…}

[10 marks]

(Functionality: 6, Design: 2, Ease of use: 1, Presentation: 1)

In both methods errors should be handled properly. For example what happens

when adding an element to a full queue?

There will be skeleton code for MyArrayQueue available on Learning central that

contains the MyArrayQueue class with the following fully implemented methods:

constructor, isEmpty(), getFrontElement(), getRearElement() methods. It also

includes signatures of two methods that you should implement: enqueue(Object

theElement) & dequeue().
