If the variable sum and product have the same value, then the given number (n) is a spy number, else not a spy number.

Repeat steps 3 to 6 until the given number (n) becomes 0.

Multiply the last digit with the product variable.

Add the last digit to the variable sum.

Find the last digit (n%10) of the given number by using the modulo operator.

Initialize sum with 0 and product with 1.

Declare two variables sum and product to store sum and product of digits.

Read or initialize a number ( n) that you want to check.

Some other spy numbers are 22, 123, 132, etc. Similarly, we can check other numbers also. We observe that the sum and product of the digits both are equal.

After that find the sum and product of all the digits. First, we will split it into digits (1, 1, 2, 4). Let's take the number 1124 and check whether the number is a spy or not. In other words, a number whose sum and product of all digits are equal is called a spy number. Spy NumberĪ positive integer is called a spy number if the sum and product of its digits are equal. The spy number program is frequently asked in Java coding test. import this section, we will learn what is a spy number and also create Java programs to check if the given number is Spy or not. Initialize the sum variable with 0 and the product variable with 1.ĥ) Multiply last digit with the product variableħ) Repeat 3 to 6 steps until the number becomes 0Ĩ) If the value of sum and product variable is equal then the given number is spy number else it is not a spy number. Procedure to develop method to check the given number is spy number or not,Ģ) Declare sum and product variables.

The product of the digits = 1 * 1 * 2 * 4 = 8 The product of the digits = 1 * 3 * 2 = 6 Python Program to Check Number is Prime Number or NotĪ number whose sum of the digits of is equal to the product of its digits is called Spy number.
