Can anyone help me in understanding the problem statement? It's so confusing.

@Dyuman
If number of digits in A, n1 = 4, then A belongs to {10^4 to 10^5-1}
You will be given n1 and n2. You need to find the sum of ( min and max number of digits ) in A*B.

Let c be the number of digits in the smallest product of an n1-digit number and an n2-digit number and d be the number of digits in the largest product of an n1-digit number and an n2-digit number. Return c+d.
