/*
You have a character who jumps forward n number of units at a time, and an array representing the road in front of them (where 0 is a flat piece of road, and 1 is an obstacle). Return true or false if your character can jump to the end without hitting an obstacle in front of them.

Trying it out in rust this time!

Example:
character_jump(3, [0,1,0,0,0,1,0]) -> true
character_jump(3, [0,1,0,1,0,1,0]) -> false
*/

fn character_jump(step_size: u32, road: &[u32]) -> bool {
    let mut index: usize = 0;
    while (index) < road.len() {
        if road[index] == 1 {
            return false;
        }
        index += step_size as usize;
    }
    true
}

fn main() {
    if character_jump(3, &[0,1,0,0,0,1,0]) == true &&
        character_jump(3, &[0,1,0,1,0,1,0]) == false &&
        character_jump(4, &[0,1,1,0,1,0,0,0,0]) == false {
        println!("All tests passed!");
    }
