Chapter 2, Problem 2.64HW
Write code to implement the following function:
/* Return 1 when any odd bit of x equals 1; 0 otherwise.
Assume w = 32 */
int any_odd_one(unsigned x);
Your function should follow the bit-level integer coding rules (page 128), except that you may assume that data type int has w = 32 bits.

Write a function that prints the ASCII values of the char- acters using the following header:
void printASCII(char ch1, char ch2, int numberPerLine)
This function prints the ASCII values of characters between ch1 and ch2 with the specified number of characters per line. Write a test program that prints 6 ASCII values per line of characters from 'a' to 'm'.
*Code in Python
A bit shift is a procedure whereby the bits in a bit string are moved to the left or to the right.
For example, we can shift the bits in the string 1011 two places to the left to produce the string 1110. Note that the leftmost two bits are wrapped around to the right side of the string in this operation.
Define two scripts, shiftLeft.py and shiftRight.py, that expect a bit string as an input.
The script shiftLeft shifts the bits in its input one place to the left, wrapping the leftmost bit to the rightmost position.
The script shiftRight performs the inverse operation.
Each script prints the resulting string.
An example of shiftLeft.py input and output is shown below:
Enter a string of bits: Hello world!
ello world!H
An example of shiftRight.py input and output is shown below:
Enter a string of bits: Hello world!
!Hello world

// Task 3
// For this function, you must return the largest power of 2 that// is less than or equal to x (which will be positive). You may// not use multiplication or some sort of power function to do this,// and should instead rely on bitwise operations and the underlying// binary representation of x. If x is 0, then you should return 0.unsigned largest_po2_le(unsigned x) {return x;}
