### Rust
> 双指针
```rust
impl Solution {
pub fn backspace_compare(s: String, t: String) -> bool {
let (s, t) = (
s.chars().collect::<Vec<char>>(),
t.chars().collect::<Vec<char>>(),
);
Self::get_string(s) == Self::get_string(t)
}
pub fn get_string(mut chars: Vec<char>) -> Vec<char> {
let mut slow = 0;
for i in 0..chars.len() {
if chars[i] == '#' {
slow = (slow as u32).saturating_sub(1) as usize;
} else {
chars[slow] = chars[i];
slow += 1;
}
}
chars.truncate(slow);
chars
}
}
```
> 双栈法
```rust
impl Solution {

Self::get_string(s) == Self::get_string(t)
}
pub fn get_string(string: String) -> String {
let mut s = String::new();
for c in string.chars() {
if c != '#' {
s.push(c);
} else if !s.is_empty() {
s.pop();
}
}
