题目给出了一个C语言子集的编译器,将用户的程序编译为MIPS汇编,使用SPIM运行。要读取flag,考虑先利用编译器的漏洞,在MIPS环境下实现任意内存地址写入,再劫持返回地址到shellcode区域,使用shellcode进行open-read-write,输出flag。 shellcode的编写 SPIM提供了少量syscall,支持基本的标准输入输出功能,以及文件的打开、读...

The WTR comparators then generate a WTR comparator output indicating whether the write index matches the read index to control a WTR function. In this manner, the WTR comparator circuit can employ less WTR comparators than the number of read and write port combinations. Providing less WTR ...
expect(object).toExclude(value, [comparator], [message]) expect(string).toExclude(value, [message]) Asserts that a givenvalueis not included (or "contained") within another. Theactualvalue may be an array, object, or a string. Thecomparatorfunction, if given, should compare two objects and...

通过Function Reference的机制,进一步改善表达力。 Collections.sort(persons, comparing(Person::getName())) 其中,Comprator.compring的实现为: @FunctionalInterface public interface Comparator<T> { int compare(T o1, T o2); static <T, U extends Comparable<? super U>> Comparator<T> ...
The methods are virtually identical and could have been merged into one with the introduction of a DefaultComparator that would use the Comparable method. The strategy pattern would have avoided this design flaw. "What is good code? I find it easier to classify 'goodness' by using good object...
output two comparators as input of an AND gate, and output AND gate as extern interrupt input of MCU. Because we did not find an AND gate chip during the test, we used triode to build an AND gate. But it was unstable, so we only have to use one comparator. We would like to ask...
