Join This Thread If You Want To Master Algorithms And Data Structures

I know that we have competent programmers, I know that Nigerians are smart.
Let's not waste our intelligence on scamming white women, let's use it to
build technologies and eventually make money out of them.
Let's start posting algorithmic problems, I need everyone to post any question here hard
or easy for solution. Of course, we may not be able to solve all
problems but we can do our best. Post your problems here...

RULE:

Since Nairaland does not provide us with internal IDE for code implementation,
we can use our preferred IDE like Eclipse, IntelliJ IDEA, Visual Studio IDE, Visual Studio Code, PyCharm, NetBeans etc
after writing the code in your preferred IDE, take a screenshot of it and share it here and the outputs. Please I don't
need plain text on Nairaland, I need a screenshot, it is better and more helpful.

Here is the format:

Question:
Write a program that converts a decimal number to binary one.
example 5 --> 101, 75 --> 1001011

Solution:
There might be many ways of solving this, I can only think of two ways to solve.

1. Applying repeated division by 2 and thereafter return the remainders.
2. Using bitwise operations.

I will code it using the second method, here is the screenshot of the algorithm and some outputs.

Sorry, but What is wrong with using integer.toBinaryString method

When playing games where you have to roll two dice, it is nice to know the odds of each roll. For instance, the odds of rolling a 12 are about 3%, and the odds of rolling a 7 are about 17%. You can compute these mathematically, but if you don’t know the math, you can write a program to do it. To do this, your program should simulate rolling two dice about 10,000 times and compute and print out the percentage of rolls that come out to be 2, 3, 4, ..., 12.

Nothing is wrong with it but the code has already been written by Java creators. The purpose of this thread is to help you learn how to write those codes yourself.

Secondly, I'm new to programming and I want to learn a lot.

Lastly, Nairaland bots keeps banning me if I upload any pictures here. I don't know why

Yes, that is a problem. I have similar challenge. If you have solid knowledge in data structures and algorithms you can join my coding WhatsApp group or if you are new you can subscribe to my Zoom tutorial.

I'm new to programming though.
