foo.md - Opengist

this is me testing opengist
here is some rust code
use std::cmp;

impl Solution {
    pub fn max_sub_array(nums: Vec<i32>) -> i32 {
        let mut current_subarray_sum = nums[0];
        let mut max_subarray_sum = nums[0];

        for num in &nums[1..] {
            let num = *num;

            // as we iterate through the array,
            // we increment by the next number in the "current" subarray
            // if we find that the sum of the current subarray is less
            // than the current number, we "reset" to the current number
            current_subarray_sum = cmp::max(
                num,
                current_subarray_sum + num
            );

            // meanwhile, always be keeping track of the max subarray sum
            // we've found
            max_subarray_sum = cmp::max(
                max_subarray_sum,
                current_subarray_sum
            );
        }

        max_subarray_sum
    }
}
