upper_bound Returns an iterator pointing to the first element in the range [first,last) which compares greater than val. Return value An iterator to the upper bound position for val in the range. If no element i

If we know an upper bound of the minimum distance of the code, then we have a good indication about the capabilities and the limitations of the code. One of the classes of the error correcting codes with the best performance is that of turbo codes. For such codes, establishing upper ...

范围以两个迭代器定义,一个指向首个不小于 key 的元素,另一个指向首个大于 key 的元素。首个迭代器可以换用 lower_bound() 获得,而第二迭代器可换用 upper_bound() 获得。 1,2) 将键与 key 比较。3,4) 将键与值 x 比较。此重载只有在限定标识 Compare::is_transparent 合法并指代类型时才会参与重载...
When printing within a range views pipeline using the IC_FV function, all the lower_bound, upper_bound, and index values must be positive.Tuple like typesA std::pair<T1, T2> or std::tuple<Ts...> typed variables will print all of its elements.The code:...
