4. Angle Calculation Between Clock Hands Given a specific time in hours and minutes, your task is to calculate the smallest possible angle between the hour hand and the minute hand of a clock. Example: Input: T = 2H = 3, M = 30H = 9, M = 45 Output: 75112 Explanation: In the first example, when the time is 3:30, the smaller angle between the hour and minute hands is 75 degrees. Constraints: 1 ≤ T ≤ 50 1 ≤ H ≤ 12 0 ≤ M ≤ 59 Time limit: 1 second Note: There are two potential angles between the clock hands, but you must return the minimum of these two angles. When computing the angle, return its floor value, e.g., for an angle of 15.2, you should return 15.Ensure your implemented function outputs the results as expected.
