java-dsa-bootcamp's Issues

Flow of program Q3 flowchart issue

In the following link:-
https://github.com/thatbeautifuldream/java-dsa-bootcamp/blob/main/01-flow-of-program/q3.png
Here the flowchart intialisation is wrong it should be i=1 instead of 0 which is correctly written in the pseudo code of the same.

02-first-java Programs Not Matching With Kunal's Questions

For example,
The code given in the file 02-first-java for Q1.java is the code that gives the factorial of a number. Whereas in Kunal's assignment the corresponding question is to check whether a number is odd or eve which is done in Q2.java.

I found this to be the issue for multiple questions. I would love to be assigned to fix it.

Conditionals assignment small error

In Q10 of the conditionals assignment in the answer code, you are taking the height of the parallelogram as input, it should be "side".
Simply replace "height" by "side" in the System.out.println("") statement.

Invalid LCM code

Description of the bug

The code provided in the "03-conditionals-loops/2. Intermediate Java Programs/LCM.java"
does not give the lcm insted it gives the commmon factor between the two elements

Steps To Reproduce

go to file 03-conditionals-loops/2. Intermediate Java Programs/LCM.java
and run the code

Additional Information

We can get lcm by dividing the multiplication of the number by their hcf
