rust leetcode 不明所以の报错

不知道为什么会报越界的错

自己的代码是没有问题的 😢

struct Solution;

impl Solution {
    #[allow(unused)]
    pub fn search(nums: Vec<i32>, target: i32) -> i32 {
        let mut c = core::cell::RefCell::new(nums);
        let cc = c.get_mut(); 
        cc.sort();
        let mut l = 0;
        let mut r = cc.len() - 1;
        while l <= r {
            let mid = (l + r) >> 1;
            if target == cc[mid] {
                return mid as i32;
            } else if target < cc[mid] {
                r = mid - 1;
            } else {
                l = mid + 1;
            }
        }
        -1
    }
}

#[allow(unused)]
fn main() {
    let v = vec![1, 2, 3, 4, 5];
    let v = vec![-5];
    println!("result is: {}", Solution::search(v, -5));

}

之后看了别人的题解才发先根本不用自己写 😄

nums.binary_search(&target).map_or(-1, |x| x as i32)

// 或者使用迭代器
nums.iter().position(|&x| x == target).map_or(-1, |x| x as i32)
