Unit Conversion & Dice Game Simulation

Cli usage:

Convert 10 meters to inches Convert 10 hours to minutes

cargo run -- -u 10 m in
cargo run -- -u 10 hr min

Run Dice Game Simulation 100 times Dice Game Simulation will save results to ./output/simulations/%YYYY-%MM-%DD%h_%m_%s.txt

cargo run -- -n 100

With logs

cargo run -- -n 100 -v

Results output to custom filepath

cargo run -- -n 100 -o ./hello_world.txt

If the program is ended early with Ctrl^C... The output file will be modified such that the early termination is noted and the filename includes the number of simulations completed.

cargo run -- -n 100 -o ./hello_world.txt
ls ./hello*
>>> hello_world_early_exit_992_simulations_completed.txt

Purpose

I came across a video of a Jane Street Mock Interview, and was curious to implement it in Rust. The purpose of the problem wasn't to show off DSA, but to demonstrate talking through a code exercise with an interviewer.

Problem

Given the facts, write a program to correctly answer the following queries. ''' example facts:

• m = 3.28 ft
• ft = 12 in
• hr = 60 min
• min = 60 sec example queries:
• 2m = ? in ---> answer = 78.72
• 13 in = ? m ---> answer = 0.330 (roughly)
• 13 in = ? hr ---> "not convertible!" '''

#####Dice Game Strategy Simulation Implementation of part 1 of this problem on Jane Street's youtube. ######Strategy 1: Roll if the value of the current die-result is less than the sum of the expected values of all die results greater than the current result for the current turn. ######Strategy 2: Roll if the value is less than 20. ####Unit Conversion Class Diagram
