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

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

design LP,HP,B S digital Butterworth and Chebyshev filter. All array has been specified internally,so user only need to input f1,f2,f3,f4,fs(in hz), alpha1,alpha2(in db) and iband (to specify the type of to design). This program output hk(z)=bk(z)/ak(z),k=1,2,..., ksection and the freq.
