三： 針對(duì)帶表頭結(jié)點(diǎn)的單鏈表，試編寫下列函數(shù)。 (1) 定位函數(shù)Locate：在單鏈表中尋找第i個(gè)結(jié)點(diǎn)。若找到，則函數(shù)返回第i個(gè)結(jié)點(diǎn)的地址；若找不到，則函數(shù)返回NULL。 (2) 求最大值函數(shù)max：通過一趟遍歷在單鏈表中確定值最大的結(jié)點(diǎn)。 (3) 統(tǒng)計(jì)函數(shù)number：統(tǒng)計(jì)單鏈表中具有給定值x的所有元素。 (4) 建立函數(shù)create：根據(jù)一維數(shù)組a[n]建立一個(gè)單鏈表，使單鏈表中各元素的次序與a[n]中各元素的次序相同，要求該程序的時(shí)間復(fù)雜性為O(n)。 (5) 整理函數(shù)tidyup：在非遞減有序的單鏈表中刪除值相同的多余結(jié)點(diǎn)。

說明： column_list列出要添加數(shù)據(jù)的列名。在給表或視圖中部分列添加數(shù)據(jù)時(shí)，必須使用該選項(xiàng)說明這部分列名。 DEFAULT VALUES說明向表中所有列插入其缺省值。對(duì)于具有INDENTITY屬性或timestamp數(shù)據(jù)類型的列，系統(tǒng)將自動(dòng)插入下一個(gè)適當(dāng)值。對(duì)于沒有設(shè)置缺省值的列，根據(jù)它們是否允許空值，將插入null或返回一錯(cuò)誤信息。
