線性預測與Levinson-Dubin算法實現講述

1、線性預測與Levinson-Dubin算法實現,移動端實現右側字母A-Z的滑動觸摸選擇 映射遠程端口到本地 Shell/批處理用shell將svn的提交信息生成運維使用的更新文檔 Shell/批處理用SQL語句斷開某個數據庫的所有活動連接 SQL,用udp的方式傳輸文字 ,用于填寫支付密碼的textfield int query() /掃描 int index, len, result; node *p = root; /Trie入口 result = 0; len = strlen(str); for(int i = 0; i < len; +i) index = stri - 

2、9;a' while(p->nextindex = NULL && p != root) /跳轉失敗指針 p = p->fail; p = p->nextindex; if(p = NULL) p = root; node *temp = p; /p不動，temp計算后綴串 while(temp != root && temp->count != -1) result += temp->count; temp->count = -1; temp = temp->fail; return result;/ 使用Qt

3、仿寫系統記事本/圖片輪播器，定時器使用GCD /網頁版的簡易跳舞機 int main() int num; while(1) head= tail = 0; scanf("%d", &num); if (num = 0) break; root = new node(); getchar(); for(int i = 0; i < num; +i) gets(keyword); insert(keyword); build_ac(); scanf("%s", str); printf("%dn", query(); re
