Program Plan Intro

Program Plan-

  • Initialize the header files and main() function.
  • To define the function invert(x, p, n, y) to return x with the n bits that begin at position p inverted( changing 0 to 1 and 1 to 0), leaving the other bits unchanged.
  • Finally prints the result.

Summary Introduction- The program displays the x value after inverting some bits using bitwise operators.

Program Description- The purpose of the program is todefine the function invert(x, p, n, y) to return x with the n bits that begin at position p inverted( changing 0 to 1 and 1 to 0), leaving the other bits unchanged.

Write a function invert(x,p,n) that returns x with the n bits that begin atposition p inverted (i.e., 1 changed into 0 and vice versa), leaving the others unchanged.
Q6. Write a function that takes an unsigned integer andreturns the number of '1' bits it has(also known as the Hamming weight).For example, the 32-bit integer '11' has binaryrepresentation 00000000000000000000000000001011,so the function should return 3.T(n)- O(k)   : k is the number of 1s present in binary representation.NOTE: this complexity is better than O(log n).e.g. for n = 00010100000000000000000000000000only 2 iterations are required.Number of loops isequal to the number of 1s in the binary representation."""def count_ones_recur(n): Do it.
we will pretend that bits are sent as strings (theyare not; this would be terribly inefficient). Write a function evenParity(bits) that returns True if the string bits haseven parity and False otherwise. For example, evenParity('110101')should return True and evenParity('110001') should return False
