Program Plan Intro

Method definition of rightrot(x,n):

/*function definition of right rot*/
unsignedint rightrot(unsignedint x,unsignedint n)
{

/*loop till the bit positions*/
while(n>0)
{
/*condition to rotate each bit by one position.*/
if(x&1)
{
 x =(x >>1)|~(~0U>>1);
}
else
{
 x =(x >>1);
}
 n--;
}

return x;
}

Program Plan-

  • Initialize the header files and main() function.
  • To define the function rightrot(x, n) to rotate x right by n bits.
  • Finally prints the value of x..

Summary Introduction- The program displays the x value after rotating it right by n bits.

Program Description- The purpose of the program is todefine the function rightrot(x, n) to return x with the n bits rotated towards right.

Dijkstra's Algorithm (part 1).  Consider the network shown below, and Dijkstra’s link-state algorithm. Here, we are interested in computing the least cost path from node E (note: the start node here is E) to all other nodes using Dijkstra's algorithm. Using the algorithm statement used in the textbook and its visual representation, complete the "Step 0" row in the table below showing the link state algorithm’s execution by matching the table entries (i), (ii), (iii), and (iv) with their values.  Write down your final [correct] answer, as you‘ll need it for the next question.
