Feature #9: Kth Missing Gene
Implement the "Kth Missing Gene" feature for our "Computational Biology" project.
We'll cover the following
Description
A planet has n genes, numbered 1 to n. Every species on the planet has a subset of these genes in its DNA sequence.
For a given species’ DNA, gene_A, we want to find the missing gene in a sorted order. The given DNA sequence will be sorted in strictly increasing order.
Constraints
1 <= gene_A[i] <= 10001<= k <= 1000gene_A[i] <= gene_A[j] for 1 <= i < j <= gene_A.length
The following examples may clarify this problem:
