Problem Description
Given a list of hours worked by employees and a target number of hours, determine how many employees have worked at least the target number of hours.
Key Insights
- The problem involves iterating through an array of integers representing hours worked.
- A simple comparison of each employee's hours against the target is needed.
- The constraints are manageable, allowing for a straightforward solution without optimization for large input sizes.
Space and Time Complexity
Time Complexity: O(n) - where n is the number of employees, as we need to check each employee's hours. Space Complexity: O(1) - as we use a constant amount of space to count the employees who meet the target.
Solution
To solve the problem, we will use a single loop to iterate through the list of hours. For each employee's hours, we will check if it meets or exceeds the target. We maintain a counter to keep track of how many employees meet the requirement. This approach uses an array data structure to hold the hours and simple conditional statements to perform the comparisons.
