证明:设X=(x1,…,xn )是GREEDY-KNAPSACK算法所生成的解。如果所有的xi 等于1,显然这个解就是最优解。否则,设j是使xj !=1的最小下标。由算法可知,对于1≤i<j , xj =1; 对于j<i≤n , xj =0 ; 对于i=j ,0≤xj<1。 最优解的证明 假设X不是最优解,则必定存在一个最优解Y= (y1,…,yn),...

We were finding the pivot index like(left+ right)/2. But one thing to notice that (left+ right) has a chance to lead to integer overflow. Hence a better method is to find the pivot index like below: Pivot index= left+ (right-left)/2 ...

The first couple of chapters present clever solutions to programming problems (some very old using data tape) but that is just an intro. This a guidebook on program design and architecture, much like Code Complete, but much shorter. "Algorithms and Programming: Problems and Solutions" by Shen ...
There is a lot to learn in a university Computer Science program, but only knowing about 75% is good enough for an interview, so that's what I cover here. For a complete CS self-taught program, the resources for my study plan have been included in Kamran Ahmed's Computer Sci...
