Circular Array 1. Palindrome Use python Write a method/function that takes in a circular array, its size and start index and finds whether the elements in the array form a palindrome or not. Return true if the elements form a palindrome, otherwise, return false. Example: Input: [20,10,0,0,0,10,20,30] (start =5, size=5) Output: True. Input:[10,20,0,0,0,10,20,30] (start =5, size=5) Output: False
In java language Create a class name FunWithArrays and create the following methods: consecutiveValueChecker(int arr[]): This method will not allow user to input consecutive values in an array Input: 3,4,2,1,5,5 Output: Cannot input consecutive value please input value other than 5 calcultesLongestSequence(String arr[]): This method will take a string array and calculate length of values at each index also print the word having the longest length.
Two-Dimensional ArrayInstruction:Create a java program that generates elements (randomly from 10 – 75) of a 2-dimensional array (5x5) using the Random Class then perform the following: NOTE: Please do not use the array methods available on the internet. Use the for loop, while loop or do-while loop statement in your codes.
