Function advent_of_code_2021::day_3::analyse_diagnostics

fn analyse_diagnostics(data: &Vec<usize>, length: usize) -> (usize, usize)

This solves part one, returning the pair of required values. It calculates the gamma value by iterating through each bit in the input strings and comparing the result of count_bit to the size of the data. The epsilon value is the bitwise inverse of that.

Example from puzzle specification

let test_data = vec![
    0b00100,
    0b11110,
    0b10110,
    0b10111,
    0b10101,
    0b01111,
    0b00111,
    0b11100,
    0b10000,
    0b11001,
    0b00010,
    0b01010,
];

assert_eq!(analyse_diagnostics(&test_data, 5), (22, 9));
