Solve Matrix Equations (Also for AI/ML Interns :)

Problem Overview

• Find the 1x2 vector A such that X = A * B * C, given scalar X, 2x2 matrix B, and 2x1 vector C.
• Implement findA(X, B, C) and return [A[0], A[1]] as floats.
• Constraint: A[1] = 1 - A[0].
• Linear algebra context relevant to data and ML workflows.
• From Snowflake interviews: a coding interview problem and interview question for AI/ML interns.
