3296. Minimum Number of Seconds to Make Mountain Height Zero
Explanation:
To solve this problem, we need to simulate the reduction of the mountain's height by the workers. We iterate through each worker and calculate the time taken to reduce the height by each possible amount. We then find the maximum time taken by all workers to reduce the mountain's height to zero.
- Initialize a variable
totalSecondsto 0. - For each worker, calculate the time taken to reduce the mountain's height by each possible amount using the formula given in the problem.
- Keep track of the maximum time taken by any worker to reduce the mountain's height to zero.
- Return the maximum time taken as the minimum number of seconds required for the workers to make the height of the mountain zero.
Time Complexity: O(n), where n is the number of elements in the workerTimes array.
Space Complexity: O(1) as we are using constant extra space.
:
class Solution {
public int minSeconds(int mountainHeight, int[] workerTimes) {
int totalSeconds = 0;
for (int time : workerTimes) {
int currTime = 0;
for (int x = 1; x <= mountainHeight; x++) {
currTime += time * x;
totalSeconds = Math.max(totalSeconds, currTime);
}
}
return totalSeconds;
}
