What if my bill + tip at a restaurant always summed to a number which is a palindrome? For fun, write a rust program to show some palindromic tips around the target tip percentage.
If you always do this, it could be a sort of sort of checksum :-)
So, this program will do the following:
List some possible tips that are nearby palindromes.
% cargo run
Finished dev [unoptimized + debuginfo] target(s) in 0.00s
Running `target/debug/palitip-rs`
Enter the current bill total: 32.15
Enter percentage tip to add: 20
You entered 32.15 and wish a tip of approx +20%
Some possible palindrome totals are:
add $5.58 as a tip to get $37.73 total
add $6.68 as a tip to get $38.83 total
add $7.78 as a tip to get $39.93 total
add $7.89 as a tip to get $40.04 total- needs some UI polish
- should have an api for an alternative to the cli only
Just the std::io library
