  1. How Many Hours Can You Practice Leetcode Amazon Online Assessment Test?

You need to first set up space where you can work independently and focus on spans longer than one hour.

Discover what time works best for you; maybe early morning or late at night; before office or after office.

You should spend at least one to two hours per day, or ten to fifteen hours per week.

Find out what time you have the mental energy to focus if you attend college or work in an office.

It can be different for different people. There is no right or wrong time, just find out what works for you. The timing works best for you.

Dispose of all distractions like social media, and put your phone on silent if you can for one hour.

The amount of leetcode questions you should solve depends on your experience and expertise on each topic.

You can solve 200 leetcode questions if you are capable. There are people who have solved more than 500 questions and weren’t fortunate to make it through the interview.

Some people who solved 300 questions were able to clear the interview in several companies.

You should discover what works for you. You can move on to the next topic when you feel confident enough on one.

You can reduce the number for that topic if you have already practiced some topics like DP and graph.

  1. Maintain Some Key Pointers Specific to Leetcode

Select a topic and solve problems with it and finish it before you move to another topic.

Use ratio 3:6:1 or 3:5:2 to solve easy, medium, and hard problems, and solve easy problems by sorting them on two factors.

Acceptance rate, which is the number of people solved and attempted, indicates the question is easy.

Frequency rate is the number of times questions appeared in interviews, and it is a first-class feature.

Leetcode Amazon Online Assessment Test Practice Questions and Answers

Here are sample practice questions and answers for the Leetcode Amazon Online Assessment Test to help you to effectively prepare for it:

Movies on Flight

You are on a plane and want to watch two movies during the trip.

Int movie_duration, which includes all the movie durations, is given to you.

You are also given d in minutes as the duration of the journey.

You are now asked to select two movies and the entire duration of the two movies is less than or equal to (d – 30min).

If many can be located, look for the pair of movies that have the longest total duration and take back the pair with the longest movie.



movie_duration includes 90, 85, 75, 60, 120, 150, 125
d: 250
Output from aonecode.com
[90, 125]
The greatest number within 220 (250min – 30min) is 90min + 125min = 215

K Nearest Post Offices

Given your location and a list of locations of all post offices available, find the k post offices located nearest to you.

Locations that are seen in 2D harmonizes in [X, Y], where X and Y are integers.

To find the distance between you and a post office, Euclidean distance is applied.

Let’s take your location to be [m, n] and the location of a post office is [p, q], this SquareRoot((m – p) * (m – p) + (n – q) * (n – q)) is the Euclidean distance between the office and you.

From aonecode.com, K is a positive figure much smaller than the total number of post offices given.



you: [0, 0]
post_offices include [[-16, 5], [-1, 2], [4, 3], [10, -2], [0, 3], [-5, -9]]
k = 3

Output from aonecode.com

[[-1, 2], [0, 3], [4, 3]]

Longest String Made Up Of Only Vowels

Look from a thread of lesser characters and take away two subthreads of any length at most in such a way that the remaining thread contains only these vowels here (‘a’,’e’,’i’,’o’,’u’).

Your intention is to make the most of the length of the remaining thread from a thread. After removal of at most two substrings, output the length of the remaining string.

NOTE: The answer may be 0, i.e. removing the entire string.


Input: earthproblem

Output: 2




Output: 3
