This volume is an instructor鈥檚 manual for the 4th edition of Database System Concepts by Abraham Silberschatz, Henry F. Korth and S. Sudarshan. It contains answers to the exercises at the end of each chapter of the book.

he basic idea of the method of bisection is to start with an initial interval, [a0,b0], that is chosen so that f(a0)f(b0) < 0. (This guarantees that there is at least one root of the function f(x) within the initial interval.) We then iteratively bisect the interval, generating a sequence of interva ...

Linux socket programming delves into many particulars of network programming. It is organized into five specific parts: network programming from the client perspective, The Server Perspective and Load Control, Socket objects, advanced sockets.

This algorithm is to count the dark colored pixels in the input image. This can be used in goods sorting like rice, paddy etc... in paddy or rice or other goods or products to sort out the bad or defect one we can use this algorithm. I had done this for my Masters Degree as a small part and now i am ...

With this example-driven book, you get a quick, practical, and thorough introduction to Java s API for XML Web Services (JAX-WS) and the Java API for RESTful Web Services (JAX-RS).

找一个最小的自然数，使它等于不同的两组三个自然数的三次幂之和，即找最小的x，使得：x=a*a*a+b*b*b+c*c*c = d*d*d+e*e*e+f*f*f 其中，a,b,c,d,e,f都是自然数,a<=b<=c, d<=e<=f [a,b,c]!=[d,e,f] 进一步，是否还存在另外一个自然数满足上述条件，可能的话请输出其结果 ...
