Algorithm to count number of nodes, Data Structure & Algorithms

Assignment Help:

Write an algorithm to count number of nodes in the circular linked list.                           

Ans.

Counting No of Nodes in Circular List

Let list be a circular header list in memory. This algorithm traverse and counts number of nodes in a LIST.

0.   set COUNT: = 0

1. Set PTR: = LINK [START]. {Initializes the

pointer PTR}

2. Repeat steps 3, 4, 5 while PTR  =   START;

3. COUNT = COUNT + 1

4. Set PTR = LINK [PTR]. [PTR now points to next

node]

[End of step 2 loop]

5. Exit
