Your task is to find a range L to R (inclusive) such that the number of integers in this range that satisfies the following property is equal to K:
Property: Sum of all the subsequences of digits of that number must be odd
For example, 1257 has 1 + 2 + 5 + 7 + 12 + 15 + 17 + 25 + 27 + 57 + 125 + 127 + 157 + 257 + 1257 = 2091 as the sum of all subsequences.
Find such a range with the smallest value of L. If more than one such range exists, print the range that is of the minimum length.
