385. Mini Parser
Given a nested list of integers represented as a string, implement a parser to deserialize it.
Each element is either an integer, or a list -- whose elements may also be integers or other lists.
Note: You may assume that the string is well-formed:
- String is non-empty.
- String does not contain white spaces.
- String contains only digits
0-9

.
Example 1:
Given s = "324", You should return a NestedInteger object which contains a single integer 324.
Example 2:
Given s = "[123,[456,[789]]]", Return a NestedInteger object containing a nested list with 2 elements: 1. An integer containing value 123. 2. A nested list containing two elements: i. An integer containing value 456. ii. A nested list with one element: a. An integer containing value 789.
Rust Solution
struct Solution;
use rustgym_util::*;
impl Solution {
fn deserialize(s: String) -> NestedInteger {
nested_integer!(s)
}
}
#[test]
fn test() {
let s = "324".to_string();
let res = nested_integer!("324");
assert_eq!(Solution::deserialize(s), res);
let s = "[123,[456,[789]]]".to_string();
let res = nested_integer!("[123,[456,[789]]]");
assert_eq!(Solution::deserialize(s), res);
let s = "[123,456,[788,799,833],[[]],10,[]]".to_string();
let res = nested_integer!("[123,456,[788,799,833],[[]],10,[]]");
assert_eq!(Solution::deserialize(s), res);
}
