2. 编写代码遍历 std::vector 为了去重,我们需要遍历 std::vector 中的元素。这可以通过使用迭代器或范围for循环来实现。 3. 在遍历过程中检查并去除重复元素 在遍历过程中,我们可以使用一个辅助的数据结构(如 std::unordered_set)来跟踪已经遇到的元素。如果当前元素已经在 std::unordered_set 中,则它是一个重...
在GDB中,可以使用pretty打印机来显示特定的std::vector元素。pretty打印机是GDB的一个功能,它可以将复杂的数据结构以更易读的方式显示出来。 要在GDB中显示特定的std::v...
LeetCode 26 Remove Duplicates from Sorted Array [Array/std::distance/std::unique] <c++> 给出排序好的一维数组,删除其中重复元素,返回删除后数组长度,要求不另开内存空间。 C++ 很简单的题目,但是第一发RE了,找了很久问题出在哪。最后单步调试发现vector.size()返回值是unsigned型的。unsigned型和int型数据运...
