This section contains a brief introduction to the C language. It is intended as a tutorial on the language, and aims at getting a reader new to C started as quickly as possible. It is certainly not intended as a substitute for any of the numerous textbooks on C. 2. write a recursive function FIB (n) to find out the nth element in theFibanocci sequence number which is 1,1,2,3,5,8,13,21,34,55,…3. write the prefix and postfix form of the following infix expressiona + b – c / d + e * f – g * h / i ^ j4. write a function to count the number of nodes in a binary tr

This project attempts to implement a Database using B+Tree. The project has developed a DATABASE SYSTEM with lesser memory consumption. Its API includes simple SQL Statements and the output is displayed on the screen. Certain applications for which several features of existing databases like concurrency control, transaction management, security features are not enabled. B+Trees can be used as an index for factor access to the data. Help facility is provided to know the syntax of SQL Statements.

If we have two individually sorted vectors "a" and "b" but they are not sorted with respect to each other and we want to merge them into vector "c" such that "c" is also a sorted vector. Then c=mergesorted(a,b) can be used.

考察例1 4 - 8中的1 4個點。A中的最近點對為(b,h)，其距離約為0 . 3 1 6。B中最近點對為
(f, j)，其距離為0 . 3，因此= 0 . 3。當考察
是否存在第三類點時，除d, g, i, l, m 以外
的點均被淘汰，因為它們距分割線x= 1的
距離≥ 。RA ={d, i, m}，RB= {g, l}，由
于d 和m 的比較區中沒有點，只需考察i
即可。i 的比較區中僅含點l。計算i 和l
的距離，發現它小于，因此(i, l) 是最近

問題描述
序列Z=<B，C，D，B>是序列X=<A，B，C，B，D，A，B>的子序列，相應的遞增下標序列為<2，3，5，7>。
一般地，給定一個序列X=<x1,x2,…,xm>，則另一個序列Z=<z1,z2,…,zk>是X的子序列，是指存在一個嚴格遞增的下標序列〈i1,i2,…,ik〉使得對于所有j=1,2,…,k使Z中第j個元素zj與X中第ij個元素相同。
給定2個序列X和Y，當另一序列Z既是X的子序列又是Y的子序列時，稱Z是序列X和Y的公共子序列。
你的任務是：給定2個序列X、Y，求X和Y的最長公共子序列Z。

Floyd-Warshall算法描述
1)適用范圍：
a)APSP(All Pairs Shortest Paths)
b)稠密圖效果最佳
c)邊權可正可負
2)算法描述：
a)初始化：dis[u,v]=w[u,v]
b)For k:=1 to n
For i:=1 to n
For j:=1 to n
If dis[i,j]>dis[i,k]+dis[k,j] Then
Dis[I,j]:=dis[I,k]+dis[k,j]
c)算法結束：dis即為所有點對的最短路徑矩陣
3)算法小結：此算法簡單有效，由于三重循環結構緊湊，對于稠密圖，效率要高于執行|V|次Dijkstra算法。時間復雜度O(n^3)。
考慮下列變形：如(I,j)∈E則dis[I,j]初始為1,else初始為0，這樣的Floyd算法最后的最短路徑矩陣即成為一個判斷I,j是否有通路的矩陣。更簡單的，我們可以把dis設成boolean類型，則每次可以用“dis[I,j]:=dis[I,j]or(dis[I,k]and dis[k,j])”來代替算法描述中的藍色部分，可以更直觀地得到I,j的連通情況。
