Can You Count the Bit Strings?

Problem Overview

• Convert each of k decimal integers to an n-length bit string, generate all super bitstrings by flipping any 0s to 1s, union them, and return the total unique count.
• Inputs: n (bit string length) and bitStrings (array of integers); output: integer count of unique bit strings.
• Domain: bit manipulation and combinatorics; relevant to set operations on bit patterns.
• From Snowflake interviews: a coding interview interview question and problem.
