Please solve all problems using C/C++/Java (preferred) and write a fully answered, optimized, and detailed code with comments and screenshots along with an approach on how to solve it and why that approach, and time/space complexity along with the why. 1. Given an integer, write a function in C/C++/Java (preferred) that returns the count of bits in an integer. 2. Write a function in C/C++/Java (preferred) to add the digits of an integer. 3. Write a function in C/C++/Java (preferred) to find the difference between the maximum and minimum values in an array. 4. Write an ASCII to Integer converter in C/C++/Java (preferred)? 5. Write a function in C/C++/Java (preferred) that takes a 16-bit integer as input and outputs its ASCII value. 6. Given an integer, write a function that returns the number of bits in the integer that are set in C/C++/Java (preferred).
