Question
A linked list is said to contain a cycle if any node is visited more than once while traversing the list. Given a pointer to the head of a linked list, determine if it contains a cycle. If it does, return 1. Otherwise, return 0.
Example: head refers to the list of nodes 1 → 2 → 3 → 1 → NULL. There is a cycle where node 3 points back to node 1, so return 1.
Function Description: Complete the has cycle function provided in the moodle assignment folder. It has the following parameter: • SinglyLinkedListNode pointer head: a reference to the head of the list.
Returns: • int: 1 if there is a cycle or 0 if there is not.
Note: if the list is empty, head will be null.
Input Format: The code stub reads from stdin and passes the appropriate argument to your function. The custom test cases format will not be described for this question due to its complexity. Expand the section for the main function and review the code if you would like to figure out how to create…
In C++, can I get a code example for a function that will return the intersection items for two sets. It will return/print out the shared (intersection) items for them. I am looking for an actual function preferably for a set class, comparing one instance of a set class with another, but definitely NOT a STL keyword. Thank you.
Write a function in c programming language that gets an array of points ( function is defined as :
typedef struct{
int x;
Int y;
} point;
) and sorts the array using qsort().Given two points a=(ax,ay) and b=(bx,by) we compare them as follows:
1) if (ax)2+(ay)2 < (bx)2+(by)2, then a should come before b in the sorted array.
2) if (ax)2+(ay)2 = (bx)2+(by)2, then we compare the points by the x coordinate.
Remark: For a point a=(ax,ay) the quantity ((ax)2+(ay)2)1⁄2 is the distance of a from the (0,0). That is, we sort the points according to their distance to (0,0), and if for points at the same distance, then we sort them according to the first coordinate.
You will need to implement the comparison function, and apply qsort() on the array with this comparison function.
For example:
- Input: [(3,2), (7,1), (1,1), (3,4), (5,0), (7,1)]
- Expected output: [(1,1), (3,2), (3,4), (5,0), (7,1), (7,1) ]
Explanation:(1,1) is first because 12+12=2 is the smallest(3,2)…

The input is a text file containing data about the given map. Each file begins with the number of rows and columns in the map considered as maximum latitudes and maximum longitudes respectively on the map. The character "X" in the file represents the water that means if a cell contains "X" then the traveler is not allowed to occupy that cell as this car is not drivable on water. The character "0" in the file represents the road connected island. That means if a cell contains "0" then the traveler is allowed to occupy that cell as this car can drive on roads. The traveler starts at the island located at latitude = 0 and longitude = 0 (i.e., (0,0)) in the upper left comer, and the goal is to drive to the island located at (MaxLattitude-1, MaxLongitudes-1) in the lower right corner. A legal move from an island is to move left, right, up, or down to an immediately adjacent cell…arrow_forward
