    Python code for Cycle detection

    **Works Totally well for all the test cases **

    def has_cycle(head):
    if not head or not head.next:
        return 0      
    p = q = head
    while(True):
        p = p.next 
        q = q.next
        q = q.next if (q) else None
        if(p and q and p != q):
            continue
        else:
            break
    if( p == q ):
        return 1    
    else:
        return 0
