Problem TLDR

Reverse an array #easy

Intuition

We can use two pointers or just a single for-loop until the middle.

Approach

• Careful with the corner case: exclude the middle for the even size

• try to use built-in functions

Complexity

• Time complexity:
  𝑂(𝑛)

• Space complexity:
  𝑂(1)

Code

    fun reverseString(s: CharArray) = s.reverse()

    pub fn reverse_string(s: &mut Vec<char>) {
        s.reverse()
    }
