Convert this character into digit (Not in ASCII value) and. Let us know in the comments. Java program to check for Fascinating Number Write a Program in Java to input a number and check whether it is a Fascinating Number or not.. Sign in. In this tutorial, we’ll explore multiple ways to detect if the given String is numeric, first using plain Java, then regular expressions and finally by using external libraries. Enter an integer number::192192 is a Fascinating number. If yes then increase the value of array[digit] element by 1. 10, Jun 14. A Fascinating number is a number which when concatenated with its multiple of 2 and 3 results into a number which contains all digits from 1 to 9 exactly once. Concatenating the results : 192384576. Fascinating numbers are 3 digit numbers with a unique property. We need to continue to concatenate multiple of 3 to the concatenated number. Input: N = 192 Output: Fascinating Explanation: After multiplication with 2 and 3, and concatenating with original number, number will become 192384576 which contains all digits from 1 to 9. There could be any number of zeros and are ignored. If any element of the array is zero then it means string (number) doesn’t contain that number. | ISC Computer Science | ICSE Cmputer Application May 2020 Fascinating Numbers : Some numbers of 3 digits or more exhibit a very interesting property. London has the highest number of … 192 * 2 = 384 192 * 3 = 576 Concatenating both the results with the original number, we get: “192” + “384” + “576” = 192384576. Fascinating numbers are 3 digit numbers with a unique property. Vampire number You are encouraged to solve this task according to the task description, using any language you may know. Once we're done discussing various implementations, we'll use benchmarks to get an idea of which methods are optimal. Viewed 26k times 5. In other programming languages, like Java, classes are generally used to represent linked lists as these languages support the feature of object-oriented programming. Check array[digit] is 0 or not? Hence, it could be concluded that 192 is a Fascinating Number. To check if the string contains numbers only, in the try block, we use Double's parseDouble() method to convert the string to a Double. If resulting sum is equal to 1 then, given number is a happy number. For example, consider the number 192. Note: I have tried to understand what other people have written, please do not rehash already given answers. It could be observed that ‘192384576’ consists of all digits from 1 to 9 exactly once. 12345.15 is a number. 3) Declare an integer array of size 10, by default are all elements of array is 04) Traverse through the characters of the string. Enter an integer number::12341234 is not a Fascinating number. We need to note that multiples of 111 are Nelson numbers e.g 111, 222, 333, 444, 555, 666, 777, 888 and 999. Example 2: Input: N = 853 Output: Not Fascinating Explanation: It's not a fascinating number. Fascinating Number :- The number of 3 digit or more, when we multiplied that number by 2 and 3, and product of both is concatenated with the original number, after concatenated the number contain all the digits from 1 to 9 exactly once, regardless of the number of zeros. A Number is spy number if the sum of its digits equals the product of its digits. C Program to Check if a Given String is Palindrome . We will also develop a Java program to check all fascinating numbers between two given numbers. If you have any doubts or suggestion then comment below. Programming Code: 05, May 17. Example : consider the number 1124. A vampire number is a natural number with an even number of digits, that can be factored into two integers. Example:-Number = 192Multiplying by 2 => 192 * 2 = 384Multiplying by 3 => 192 * 3 = 576Concatenation => “192” + “384” + “576” = 192384576, which contains all the digits from 1 to 9 exactly once. import java.util. When a 3 digit number is concatenated with the number multiplied by 2 and the number multiplied by 3, sometimes we get a number which contains all the digits from 1 … Design a program to accept a positive whole number and find the binary equivalent of the number and count the number of 1’s in it and display whether it is a Evil number or not with an appropriate message. 5, 6, 9… = 1 + 2 + 4 Solved programs ; papers...
