Algorithm competition Getting Started classic 3-3 product of the last three-bit exercise 3-4 Calculator Exercise 3-5 rotation

Exercise 3-3 the last three bits of the productEnter several words, enter a number of integers (which can be positive, negative, or 0), and output the last three bits of their product. These integers are mixed with a string of uppercase letters, and your program should ignore them. Tip: Try to enter a string when executing scanf ("%d").#include Summary: 1 Note overflow2 for a break in the bad, the next code

Data structure selected -2-3-4 trees (2-3-4 tree)

Summary:Ordinary BST does not guarantee a good performance after multiple operations. So we need a BST, yes. The cost of each insertion and search is a logarithmic function of the large size of the tree. The 2-3-4 tree is a kind of BST that maintains balance.2-3-4 Tree IntroductionTo ensure that BST is balanced, we nee

Common ratios At the beginning of the information age of 195x, the most notable feature is that analog technology has turned to digital technology, graphic design has been gradually led by electronic devices from paper to media, and the granularity units have changed, but this is not so much for designers, the problem is the ratio. Aspect ratio, which is the height ratio, only discusses the three most common categories: photography, video, and display equipment. The common rates of photograph

Java divides the memory into 4 parts 1. Code area 1, Stack area 3, heap 4, static zone

1, the stack area (stacksegment)-Automatically allocated by the compiler release, stored function parameters value, local variable value, etc., the system automatically releases the JVM memory resources after the execution of the method is completed.2. Heap area (heapsegment)-typically released by programmers, storing objects and arrays created by new, the JVM does not periodically view this object, and if no reference points to the object, it is recycled3. Static zone (datasegment)-holds global
