This document outlines the interview question for the second round of the PriceLine interview for the Software Development Engineer (SDE1) position.

You are given a list of stations with associated distances and costs, where the cost includes both a fixed component and a variable component per kilometer. Your task is to calculate the cost of traveling from the source (SRC) station to the destination (DEST) station.

• List of stations with their corresponding distances and costs.

Calculate and output the total cost of traveling from the source station to the destination station.

Consider the following example:

Station List:

• Station A: Distance - 50 km, Cost - $30 (Fixed) + $1 (Per Km)
• Station B: Distance - 80 km, Cost - $40 (Fixed) + $0.8 (Per Km)
• Station C: Distance - 120 km, Cost - $50 (Fixed) + $0.7 (Per Km)
• Source Station: A
• Destination Station: C

• Implement a function or algorithm to solve the problem.
• Provide any additional details or assumptions made during the implementation.
• Feel free to discuss your approach, optimizations, and any challenges faced during the interview process.
