Introduction

In this blog post, we will explore how to solve the LeetCode problem "2651" using AI. LeetCode is a popular platform for preparing for coding interviews, and with the help of AI tools like Chatmagic, we can generate solutions quickly and efficiently - helping you pass the interviews and get the job offer without having to study for months.

Problem Statement

You are given a positive integer arrivalTime denoting the arrival time of a train in hours, and another positive integer delayedTime denoting the amount of delay in hours. Return the time when the train will arrive at the station. Note that the time in this problem is in 24-hours format. Example 1: Input: arrivalTime = 15, delayedTime = 5 Output: 20 Explanation: Arrival time of the train was 15:00 hours. It is delayed by 5 hours. Now it will reach at 15+5 = 20 (20:00 hours). Example 2: Input: arrivalTime = 13, delayedTime = 11 Output: 0 Explanation: Arrival time of the train was 13:00 hours. It is delayed by 11 hours. Now it will reach at 13+11=24 (Which is denoted by 00:00 in 24 hours format so return 0). Constraints: 1 <= arrivaltime < 24 1 <= delayedTime <= 24

Explanation

• Calculate the sum of arrivalTime and delayedTime.
  • Use the modulo operator (%) to ensure the result is within the 24-hour format (0-23).

• Runtime Complexity: O(1), Storage Complexity: O(1)

Code

    def findDelayedArrivalTime(arrivalTime: int, delayedTime: int) -> int:
    """
    Calculates the delayed arrival time in 24-hour format.

    Args:
        arrivalTime: The original arrival time.
        delayedTime: The delay in hours.

    Returns:
        The delayed arrival time in 24-hour format.
    """
    return (arrivalTime + delayedTime) % 24
