Ex4-22 單射函數(shù)問題 « 問題描述： 設(shè)函數(shù)f將點集S = {0,1, , n -1}映射為f (S) = { f (i) | iÎ S} Í S 。單射函數(shù)問題要 從S中選取最大子集X Í S 使f (X )是單射函數(shù)。 例如，當(dāng)n=7， f (S) = {1,0,0,2,2,3,6} Í S 時， X = {0,1,6} Í S 是所求的最大子集。 « 編程任務(wù)： 對于給定的點集S = {0,1, , n -1}上函數(shù)f，試用抽象數(shù)據(jù)類型隊列，設(shè)計一個O(n)時 間算法，計算f的最大單射子集。 « 數(shù)據(jù)輸入： 由文件input.txt 提供輸入數(shù)據(jù)。文件的第1 行有1 個正整數(shù)n，表示給定的點集 S = {0,1, , n -1}。第2 行是f (i)的值，0 £ i < n。 « 結(jié)果輸出: 程序運行結(jié)束時，將計算出的f的最大單射子集的大小輸出到output.txt中。 輸入文件示例 輸出文件示例 input.txt 7 1 0 0 2 2 3 6 output.txt 3

The CoinUtils project is a collection of open-source utilities developed and used by a variety of other projects in the COIN-OR repository. The project includes classes for storing and manipulating sparse matrices and vectors, performing matrix factorization, parsing input files in standard formats, building representations of mathematical programs, comparing floating point numbers with a tolerance, performing simple presolve operations, and warm starting algorithms for mathematical programs, among others.

Description 為了宣傳本次“網(wǎng)宿科技杯”廈門大學(xué)第五屆程序設(shè)計競賽，系里面做了兩張精美的海報。經(jīng)過了精確的計算，為了達到最佳美觀效果，每張海報都有自己最佳的粘貼位置。但是現(xiàn)在問題是，如果兩張海報都要求貼在最佳位置時，很有可能有部分地方會重疊在一起。現(xiàn)在您來判斷一下這兩張海報是否重疊。 Input 輸入包含兩行，每一行有四個整數(shù)來描述這個海報的最佳粘貼位置，X,Y,W,H(-10000<= X,Y <= 10000)(0 < W, H <= 10000)，X,Y表示海報左下角的坐標(biāo)，W,H分別表示寬度和高度。 Output 輸出"Yes"表示兩張海報互相重疊(表示存在一個面積大于0的公共區(qū)域)，否則輸出"No"。(不包含引號，注意大小寫) Sample Input -10 -10 20 30 0 0 30 20 Sample Output Yes

Multirate filters provide a practical approach to designing and implementing finite response (FIR) filters with narrow spectral constraints. By changing the input data rate at one or more intermediate points the filter lengths and computational rates can be greatly reduced when compared to a standard single-rate filter implementation.
