Modular Exponentiation in java

Next Letter The function accepts two characters ‘ch1’ and ‘ch2’ as the argument. ‘ch1’ and ‘ch2’ are alphabetical letters. Implement the function to find and return the next letter so that distance between ch1 and ch2. While counting distance if you exceed the letter ‘z’ then count the remaining distance starting from the letter ‘a’.

Superior Array Element In an array, a superior element is one that is greater than all elements to its right. the rightmost element will always be considered as a superior element. Here, the function accepts an integer array ‘arr’ and its length ‘n’. Implement the function to find and return the number of superior element

String Palindrome Write a function to find if the given string string is palindrome or not. Return 1 if the input string is a palindrome, else return 0. Input specification:Input 1: A string of characters. Output Specification:0 or 1 depending on whether the string is a palindrome or not. Example 1:Input 1: level Output: 1Explanation:The

Largest Sub Array Given an array containing only 0’s and 1’s, Find the largest subarray containing an equal number of 0s and 1s. Input specification:Input 1: The length of an array.Input 2: Array containing 0s and 1s. Output Specification:Return the length of the largest sub-array containing equal no. of 0s and 1s. Example 1:Input 1:

Quadratic Equation Roots Write a function to calculate roots of a quadratic equation of the from ax^2+bx+c=0The formula to find the roots of a quadratic equation is given below:X+ = (-b + root of (b^2 – 4ac))/2aX- = (-b – root of (b^2 – 4ac))/2a Input specification:Input 1: A double value representing the coefficient value

Sum of Uncommon Elements The function accepts two integer arrays ‘arr’ and ‘arr2’ of sizes n and m respectively as its argument. Implement the function to find and return the sum of all uncommon elements in two arrays (elements which are present in only one of the array).Note:Return -1 if both arrays are null (None

Straight Line Given a set of points in a plane, check weather the points lie on a straight line or not. If the lie on a straight line return the equation else return 0. Input specification:Input 1: First Line contains no of points in the plane.Input 2: Second line contains x,y coordinates of all the

Turn Off Bit The function accepts a positive integer array ‘n’ and position of the bit to be turned off ‘k’. Implement the function to turn off the kth bit of the binary representation of ‘n’ and return decimal equivalent of the obtained number. Consider position of ‘k’ according to “little Endian’ notation (i.e. right

Array Permutation The function accepts an integer array ‘arr’ of length ‘size’ as the argument. Implement the function to find and return the maximum number that can be formed by any permutation or arrangement of the digits obtained from all the numbers present in the array. You have to return the number formed as a
