Program to Find Three-Digit Numbers with Unique Digits and Divisible by Seven

Here's a program written in the BASIC programming language to find all three-digit numbers with unique digits that are divisible by seven, as well as the sum of their digits.

10 FOR i = 100 TO 999
20   a = INT(i / 100)
30   b = INT((i MOD 100) / 10)
40   c = i MOD 10
50   IF a <> b AND a <> c AND b <> c THEN
60     IF i MOD 7 = 0 AND (a + b + c) MOD 7 = 0 THEN
70       PRINT i
80     END IF
90   END IF
100 NEXT i

Explanation: - The program uses a `FOR` loop to iterate through all three-digit numbers from 100 to 999. - Inside the loop, the number is divided into its hundreds, tens, and units place digits using integer division and modulo operations. - The `IF` statement checks if all three digits are unique (i.e., not equal to each other). - If the digits are unique, the program checks if the number is divisible by seven (`i MOD 7 = 0`) and if the sum of its digits is also divisible by seven (`(a + b + c) MOD 7 = 0`). - If both conditions are met, the number is printed.

Please note that the program provided is written in the BASIC programming language. If you want to run it on a specific platform or in a specific environment, you may need to adjust the syntax or use a different programming language.
