Fascinating Number in Java
---------------------------------------------------
In this section, we will learn what is a fascinating number and also create Java programs to check if the given number is fascinating or not. The fascinating number program is frequently asked in Java coding tests.
Fascinating Numbers
---------------------------------------------------
Multiplying a number by two and three separately, the number obtained by writing the results obtained with the given number will be called a fascinating number. If the result obtained after concatenation contains all digits from 1 to 9, exactly once.
In other words, we can also say that a number (n) may be a fascinating number if it satisfies the following two conditions:
If the given number is a 3 or more than three-digit
If the value getting after concatenation contains all digits from 1 to 9, exactly once.
For example, 192, 1920, 2019, 327, etc. Let's understand the concept of fascinating numbers through an example.
Fascinating Number Example
Let's take any number (n) say 327 and check whether the given number is fascinating or not. On multiplying the given number (n) by 2 and 3, we get:
327×2=654
327×3=981
Now, concatenate the above results to the given number (n).
"327"+"654"+ "981"= 327654981
We observe that the resultant () contains all the digits from 1 to 9, exactly once. Hence, the given number 327 is a fascinating number. Note that, we have not added the result to the given number. Some other fascinating numbers are 192, 219, 273, 327, 1902, 1920, 2019 etc.
