[ashukr07]

Description

Added code snippets for C++:

1. Math and Number Category snippets:

   • Binary to decimal conversion
   • Check if the number is perfect number
   • Calculate the factorial of a number using recursion
   • Find the nth fibonacci number using recursion
   • Calculate greatest comman divisor(GCD)
   • Calculate the least comman multiple(LCM)
   • Calculate the sum of digits of a number

2. Added new Bit Manipulation Category

   • Check if a given number is power of 2
   • Count set bits in a number
   • Find the non repeating number in array
   • Reverse bits
   • Calculate the XOR over 1 to n(provided by user)

3. Added new Searching Category

   • Linear Search
   • Binary Search

4. Added new Sorting Category

   • Bubble sort
   • Insertion sort
   • Merge sort
   • Quick sort
   • Selection sort

A lot of the bit manipulation should be moved to C. They are not exactly specific for C++, except for the vector one.
C++ STL provides functions for sorting and searching. They don't need to be in the Snippets.

Ok I will remove the searching and sorting part from the snippets.
But for bit manipulation it is not only for c, we could also do bit manipulation in C++. So we could keep that in both the languages

Hey, I understand that bit manipulation isn't exclusive to C and can also be done in C++. However, since the snippets don't use any C++-specific features (at least no big one) and are more aligned with C-style programming, it makes sense to categorize them under C.

Got it, thanks for pointing out. I’ll make the changes to categorize the snippets under C accordingly.

I have moved all the snippets of bit manipulation to C except the find the non repeating element in vector as vector is supported only in C++.
I have also removed the searching and sorting snippets and gcd and lcm snippets as it is present in C++ stl.

Some little misplacements of files, but overall great work

All the mentioned snippets moved to C

Great work thanks !
