Question

Trying to create a program using following algorithms.

JumpSearch(list,lower,upper,jump,x)
{Look for X in List[lower ... upper].
Report its position if found, else report 0. List is sorted in increasing order.
upper>=lower>0; upper-lower+1>=jump>=1.}
index = lower + jump -1
while upper > index and x> list [index]
index = index + jump
if upper > index
upper = index
LinearSearch(list,index-jump+1, upper, x)

This is so far I have, I don't the program is not correct. Can anyone help me complete it or guide it so that I can complete it.

{
class Program
{
public int JumpSearch (int[] list, int lower, int upper, int jump, int X)
{


int index = lower + jump - 1;
while (upper > index && X > list[index])
{
index = index + jump;
}

if (upper > index)
{ upper = index; }

return -1;
}





static void Main(string[] args)
{
int Index;
int Item;
int lower = 0, upper = 9;
int[] list = new int[10] {1,2,3,4,5,6,7,8,9,10};



Console.WriteLine("\nEnter the number you want to search the position.\n");
Item = int.Parse(Console.ReadLine());
Program p = new Program();
Index = p.JumpSearch(list, lower, upper, Item,1);
if (Index == -1)
{
Console.WriteLine("The number you entered could not be found. Please enter different number from the list.");
}
else
{
Console.WriteLine("The number you entered is found at {0} position in the list.", Index);
}
Console.ReadLine();
}

}
}
