`Reverse Integer– LeetCode Problem`

### Problem:

Given a signed 32-bit integer `x`, return `x` with its digits reversed. If reversing `x` causes the value to go outside the signed 32-bit integer range `[-231, 231 - 1]`, then return `0`.

Assume the environment does not allow you to store 64-bit integers (signed or unsigned).

Example 1:

```Input: x = 123
Output: 321
```

Example 2:

```Input: x = -123
Output: -321
```

Example 3:

```Input: x = 120
Output: 21
```

Constraints:

• `-231 <= x <= 231 - 1`

```class Solution {
public:
int reverse(int x) {
long ans = 0;

while (x) {
ans = ans * 10 + x % 10;
x /= 10;
}

return (ans < INT_MIN || ans > INT_MAX) ? 0 : ans;
}
};```
```class Solution {
public int reverse(int x) {
long ans = 0;

while (x != 0) {
ans = ans * 10 + x % 10;
x /= 10;
}

return (ans < Integer.MIN_VALUE || ans > Integer.MAX_VALUE) ? 0 : (int) ans;
}
}```
```class Solution:
def reverse(self, x: int) -> int:
ans = 0
sign = -1 if x < 0 else 1
x *= sign

while x:
ans = ans * 10 + x % 10
x //= 10

return 0 if ans < -2**31 or ans > 2**31 - 1 else sign * ans```
