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.

設B是一個n×n棋盤,n=2k,(k=1,2,3,…)。用分治法設計一個算法,使得:用若干個L型條塊可以覆蓋住B的除一個特殊方格外的所有方格。其中,一個L型條塊可以覆蓋3個方格。且任意兩個L型條塊不能重疊覆蓋棋盤

[輸入] 圖的頂點個數N,圖中頂點之間的關系及起點A和終點B [輸出] 若A到B無路徑,則輸出“There is no path” 否則輸出A到B路徑上個頂點 [存儲結構] 圖采用鄰接矩陣的方式存儲。 [算法的基本思想] 采用廣度優先搜索的方法,從頂點A開始,依次訪問與A鄰接的頂點VA1,VA2,...,VAK, 訪問遍之后,若沒有訪問B,則繼續訪問與VA1鄰接的頂點VA11,VA12,...,VA1M,再訪問與VA2鄰接頂點...,如此下去,直至找到B,最先到達B點的路徑,一定是邊數最少的路徑。實現時采用隊列記錄被訪問過的頂點。每次訪問與隊頭頂點相鄰接的頂點,然后將隊頭頂點從隊列中刪去。若隊空,則說明到不存在通路。在訪問頂點過程中,每次把當前頂點的序號作為與其鄰接的未訪問的頂點的前驅頂點記錄下來,以便輸出時回溯。 #include<stdio.h> int number //隊列類型 typedef struct{ int q[20]

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。
