>>156　やってみた。バブルソートだけど、いいかなあ・・・
Pop *Sort(Pop *top){
Pop dummy_top;//ダミーの先頭を作る
dummy_top.pop = 0;
dummy_top.NextPtr = top;

Pop *p_search = dummy_top.NextPtr;//検索対象
Pop *p_replace = &dummy_top;//置き換え対象(比較対象)の一つ前
while(p_search != NULL){
while(p_replace->NextPtr != p_search){
if(p_replace->NextPtr->pop > p_search->pop){
//置き換える
Pop *search_next = p_search->NextPtr;
Pop *replace_next = p_replace->NextPtr;
Pop *replace_next_next = p_replace->NextPtr->NextPtr;
p_search->NextPtr = replace_next;
p_replace->NextPtr->NextPtr = search_next;//p_replace->NextPtrより先に置き換えること
p_replace->NextPtr = replace_next_next;
//最初に戻して繰り返し
p_search = dummy_top.NextPtr;
p_replace = &dummy_top;
break;
}
p_replace = p_replace->NextPtr;
}
p_search = p_search->NextPtr;
