Take the lead junction point of the singly-linked list h prior to the i-th data elements insert a data element x, single linked list, you first need to find the first i-1 junction point and indicated pointer p, and then apply for a pointer s instructions the knot point of space, and set the x its data field values, last modified i-1 nodes, and x node pointer to the i-th node, delete the i-th to take the lead in a single linked list node h node, we must first count and looking to the i-th node pointer p points to its precursor i-1 nodes, then delete the i-th node and release deleted node space.
