Problem Overview

• Compute the total time to type a text on a single-row keyboard based on finger movement between indices.
• Input: keyboard (26 unique lowercase letters) and text; start at index 0; movement time is abs(j - i).
• Output: an integer total time; constraints: text length 1–100,000 and letters are a–z.
• Simulates typing on a custom layout; a Google interviews problem and a common coding interview interview question.
