Smallest Number with Given Digit Product
Given a positive integer 'N', find and return the smallest number 'M', such that the product of all the digits in 'M' is equal to 'N'. If such an 'M' is not possible or if 'M' cannot fit in a 32-bit signed integer, return 0.
Example:
Input:
N = 90
Output:
259
Explanation:
For 'N' = 90, the possible values for 'M' include 259 (2*5*9 = 90), 3352 (3*3*5*2 = 90), 2335 (2*3*3*5 = 90), and 952 (9*5*2 = 90), among others. The smallest possible 'M' is 259, hence, the answer is 259.
Constraints:
- 1 <= T <= 1000
- 1 <= N <= 109
- Time limit: 1 sec
