Happy number in java icse

Problem: Write a java program to determine whether a given number is happy or not. In number theory, a happy number is a number that eventually reaches 1 when replaced by the sum of the square of each digit. Wikipedia. For example: 7. Whereas the numbers, whose sum of the square of each digit results in 4 are sad or unhappy numbers. JAVA Notes - Soms Java. Introduction.

Input a sentence from the user and count the number of times, the words "an" and "and" are present in the sentence. Design a class Frequency using the description given below: [ 10] Class name: Frequency Data members/variables: text: stores the sentence. Hence, 28 is a happy number. Example: 12 = (1) 2 + (2) 2 = 1 + 4 = 5 Hence, 12 is not a happy number. Design a class Happy to check if a given number is a happy number. Some of the members of the class are given below: Class name: Happy Data Members/instance variables: n: stores the number Member functions Happy( ): constructor to assign 0 to n. Procedure to check the given number is kaprekar number or not. 1) Take a number. 2) Find its square value. 3) Count the number of digits in the square. 7) Check any part having only 0, if yes then skip the iteration. 8) Calculate the sum of both parts. 9) Compare sum and number, if both are equal then the given number is kaprekar number. Write a Java program to check whether a given number is a Disarium number or unhappy number. A Disarium number is a number defined by the following process: Sum of its digits powered with their respective position is equal to the original number. For example 175 is a Disarium number: As 1 1 +3 2 +5 3 = 135. Some other DISARIUM are 89, 175, 518 etc. 2018. 5. 14. · Input 9, It's square = 81 = 8+1 = 9 ( So 9 is a Neon Number ) Input 25, It's square = 625 = 6+2+5 = 13 ( So 25 is not a Neon Number ) Write a program to find and print neon numbers from different given numbers. this program should terminate / stop it's processing when a negetive number is given as input. Use "for loop" for finding the sum of. Student Zone.

The number of variables isn't that bad. The problem is, rather, that i, j, k, and n are cryptic and headache-inducing. The headache remedy would be to introduce a helper function and rename the variables to be more meaningful. Java program to find the LCM of two numbers. L.C.M. or Least Common Multiple of two values is the smallest positive value which the multiple of both values. For example multiples of 3 and 4 are: 3 → 3, 6, 9, 12, 15 ... 4 → 4, 8, 12, 16, 20 ... The smallest multiple of both is 12, hence the LCM of 3 and 4 is 12.

Fascinating Numbers : Some numbers of 3 digits or more exhibit a very interesting property. The property is such that, when the number is multiplied by 2 and 3, and both these products are concatenated with the original number, all digits from 1 to 9 are present exactly once, regardless of the number of zeroes. Happy number in java icse There could be any number of zeros, but they are ignored. Such a 3 digit number is known as a fascinating number. Let us look at an example. Consider the number 273. Following are the multiples of 2 and 3 of the number 273. 1 x 273 = 273. 2 x 273 = 546. 3 x 273 = 819. An Automorphic number is a number whose square “ends” in the same digits as the number itself. Examples: 5*5 = 25, 6*6 = 36, 25*25 = 625 b. tech. bca. Repeat the process until the number equals 1 (where it will stay), or it loops endlessly in a cycle which does not include 1. Those numbers for which this process ends in 1 are happy. Return true if n is a happy number, and false if not. Input: n = 19 Output: true Explanation: 1 2 + 9 2 = 82 8 2 + 2 2 = 68 6 2 + 8 2 = 100 1 2 + 0 2 + 0 2 = 1. Starting with any positive integer, replace the number by the sum of the squares of its digits, and repeat the process until the number equals 1 (where it will stay), or it loops endlessly in a cycle that does not include 1.
