Solutions to HackerRank Coding Challenges in Python

One of the best ways to absorb and retain new concepts that I have learnt about coding in Python is through documentation! As part of my journey to future-proof my data career and also to improve my proficiency in the python language, I have spent some of my free time to solve coding challenges on HackerRank . In this blog post, I shared the solutions to some of the practice challenges which I have completed and successfully passed the code in the compiler on HackerRank . Do click on Read More or the title of this blog post for the Python 3 solutions which I have created.

Arithmetic Operators

Print function, write a function, python introduction (easy) questions.

Given an integer, n , perform the following conditional actions:

• If n is odd, print Weird
• If n is even and in the inclusive range of 2 to 5 , print Not Weird
• If n is even and in the inclusive range of 6 to 20 , print Weird
• If n is even and greater than 20 , print Not Weird

Input Format: A single line containing a positive integer, n .

Constraints:

• 1 <= n <= 100

Output Format: Print Weird if the number is weird. Otherwise, print Not Weird .

The provided code stub reads two integers from STDIN, a and b . Add code to print three lines where:

• The first line contains the sum of the two numbers.
• The second line contains the difference of the two numbers (first - second).
• The third line contains the product of the two numbers.

Print the following:

Input Format: The first line contains the first integer, a . The second line contains the second integer, b .

Output Format: Print the three lines as explained above.

Sample Input 0

Sample Output 0

The provided code stub reads two integers from STDIN, a and b . Add logic to print two lines. The first line should contain the result of integer division, a//b . The second line should contain the result of float division, a/b .

No rounding or formatting is necessary.

• The result of the integer division 3//5 = 0 .
• The result of the float division is 3/5 = 0.6 .

Input Format

The first line contains the first integer, a . The second line contains the second integer, b .

Output Format

Print the two lines as described above.

The provided code stub reads and integer, n , from STDIN. For all non-negative integers i < n , print i**2 .

The list of non-negative integers that are less than n = 3 is [0,1,2] . Print the square of each number on a separate line.

Input Format: The first and only line contains the integer, n .

Constraints: 1 <= n <= 20

Output Format: Print n lines, one corresponding to each i .

The included code stub will read an integer, n , from STDIN.

Without using any string methods, try to print the following: 123 . . . n

Note that “…” represents the consecutive values in between.

Example n=5

Print the string 12345 .

Input Format: The first line contains an integer n .

Constraints: 1 <= n <= 150

Output Format: Print the list of integers from 1 through n as a string, without spaces.

Python Introduction (Medium) Questions

An extra day is added to the calendar almost every four years as February 29, and the day is called a leap day. It corrects the calendar for the fact that our planet takes approximately 365.25 days to orbit the sun. A leap year contains a leap day.

In the Gregorian calendar, three conditions are used to identify leap years:

• The year can be evenly divided by 100, it is NOT a leap year, unless:
• The year is also evenly divisible by 400. Then it is a leap year. This means that in the Gregorian calendar, the years 2000 and 2400 are leap years, while 1800, 1900, 2100, 2200, 2300 and 2500 are NOT leap years.

Given a year, determine whether it is a leap year. If it is a leap year, return the Boolean True , otherwise return False .

Note that the code stub provided reads from STDIN and passes arguments to the is_leap function. It is only necessary to complete the is_leap function.

Input Format: Read year , the year to test.

Constraints

1900 <= year <= 10 ** 5

Output Format: The function must return a Boolean value (True/False). Output is handled by the provided code stub.

Explanation 0

1990 is not a multiple of 4 hence it’s not a leap year.

HackerRank Python Solutions

    HackerRank Python Solutions

HackerRank is a platform designed to help you improve your coding skills by solving coding problems and challenges. It’s essential to practice and learn on your own to build a strong foundation in programming.

If you’re looking to improve your Python skills on HackerRank, here are some general tips:

• Start with Easy Problems : Begin with the easier problems on the platform to get familiar with the problem-solving process and Python syntax.
• Read the Problem Statement Carefully : Make sure you fully understand the problem before attempting to solve it. Identify the input format, output format, and any constraints.
• Plan Your Approach : Think about the different algorithms or data structures that could be applied to solve the problem efficiently.
• Write Modular Code : Break down the problem into smaller subproblems and write modular, reusable functions.
• Test Your Code : After writing the code, test it with different test cases to ensure it produces the correct output.
• Optimize : If your initial solution works but is slow, try optimizing it to run within the given time constraints.
• Learn from Others : Even though I can’t provide solutions directly, you can learn a lot by examining the solutions of others on the platform after you’ve attempted a problem.
• Practice Regularly : The more you practice, the better you’ll get at problem-solving and coding in Python.

Remember, the real value of platforms like HackerRank comes from the learning process and the skills you develop along the way. Happy coding!
