This approach involves iterating through both releaseTimes and keysPressed to calculate the duration of each keypress. We'll track the maximum duration found so far and update our result each time we find a keypress with a longer duration. If two keypresses have the same duration, we choose the lexicographically larger key.
Time Complexity: O(n), where n is the length of the releaseTimes array. We iterate through the list once.
Space Complexity: O(1), as we only use constant extra space for variables.

2 let maxDuration = releaseTimes[0];
3 let result = keysPressed[0];
4 for (let i = 1; i < releaseTimes.length; i++) {
5 let duration = releaseTimes[i] - releaseTimes[i - 1];
6 if (duration > maxDuration || (duration === maxDuration && keysPressed[i] > result)) {
7 maxDuration = duration;

14console.log(slowestKey([12,23,36,46,62], "spuda"));The JavaScript version, similar to its counterparts, uses a for loop to evaluate the duration of each key press and decides the resulting character based on predefined rules.
In this approach, we create a temporary array to store the duration of each key press. We then iterate over this array to find the maximum duration. This solution separates the concerns of calculation and comparison for more clarity.
Time Complexity: O(n)
Space Complexity: O(n) due to additional array usage.
