A Pandigital Number is number which makes the use of all digits 1 to 9 exactly once. We are given a number, we need to find if there are two numbers whose multiplication is given number and given three numbers together are pandigital.
Input : 7254 Output : Yes 39 * 186 = 7254. We can notice that the three numbers 39, 186 and 7254 together have all digits from 1 to 9. Input : 6952 Output : Yes
The idea is to consider all pairs that multiply to given number. For every pair, create a string containing three numbers (given number and current pair). We sort the created string and check if sorted string is equal to “123456789”.
