Imagine a bunch of pairwise distinct integer numbers a[0], a[1] , ..., a[n - 1] placed on a circle in the same order. There are n pairs of neighboring numbers: (a[o], a[1]) (a[1], a[2]). (a[n - 2], a[n - 1]), (a[n 1], a[0]) 1 2 3 4 } You tried to encode the circle of numbers by recording the pairs, but unfortunately the numbers in these pairs got shuffled, so now each pair (x, y) could be represented either as (x, y) or (y, x). You are given an array pairs of these shuffled pairs, and your task is to return the initial state of the numbers on the circle. Please, note that any cyclic rotation of the initial state is also considered to be a correct

Ayear in the modern gregorian calendar consists of 365 days. in reality, the earth takes longer to rotate around the sun. to account for the difference in time, every 4 years, a leap year takes place. a leap year is when a year has 366 days: an extra day, february 29th. the requirements for a given year to be a leap year are: the year must be divisible by 4if the year is a century year (1700, 1800, the year must be evenly divisible by 400some example leap years are 1600, 1712, and 2016.write a program that takes in a year and determines whether that year is a leap year. ex: if the input is 1712, the output is: 1712 is a leap year. ex: if the input is 1913, the output is: 1913 is not a leap year.

What makes myhexadecimalnumber a child of mynumber? which methods does myhexadecimalnumber inherit directly from the mynumber class? what can an instance of the mynumber class do? what can an instance of the myhexadecimalnumber class do? which methods are overridden? why are they overridden? how many examples of overloading are there? why was this done? where is the super keyword used? what is it doing? why isn’t the incoming value set immediately in the second myhexadecimalnumber constructor? how many examples can you find of an inherited method being called?
