100,000,000 integers in range [0, 1e6) 2098 17265.4 As you can see, radix sort is faster than the default std::sort function in C++ for most of the test cases. Conclusion Radix sort is a powerful sorting algorithm that can be used to sort elements faster than many other sorting alg...

However we define it, the comparision function must have the following properties: - Two keys cannot both be "less than" each other; if k1 is "less than" k2, then k2 must never be "less than" k1. - If k1 is "less than" k2 and k2 is "less than" k3, then k1 must be "less...

但是这样改却引起了程序的crash。 根据经验,crash在std底层库,那肯定是一些通用性的问题,于是在谷歌上检索到这么一条有用信息。实现std::sort的比较函数 lessThan(const T& left, const T& right) {/满足严格排序/} 需要满足以下规则。 strict weak ordering ...
Edit & run on cpp.sh Things to know When we use the sort function to sort an array our arguments will look a bit different then when we use it on a vector for example. In the example above when we pass in intArray as an argument we are telling the function to start the sort at...
