WAP to delete node in singly linked list when position and start pointer is given. Without using extra pointer

1:  typedef struct list_  
2:  {  
3:     struct list_ *next;  
4:     int data;  
5:  }list_t;

7:  {  
8:    if ( NULL == node)  
9:    {  
10:      printf("Position not found\n");  
11:      return;  
12:    }
