TestDome C++恶意代码分析问题求助：末尾元素替换错误

我在练习恶意代码分析相关编程题时，模拟恶意程序的最后一步（将指定位置元素替换为0）遇到瓶颈。程序前序逻辑输出均符合预期，但末尾部分本该输出3, 3, 0，实际却得到0, 0, 0。

以下是我的代码：

#include <iostream>
#include <iterator>
#include <vector>
#include <algorithm>

// Update: The problematic is that we need to find a way to not eliminate the first two 77 values.

std::vector<int> simulate(const std::vector<int>& entries) {
    std::vector<int> tempEntries{};
    std::vector<int> simEntries{ entries };

    for (std::vector<int>::const_iterator itX = entries.begin();
        itX != entries.end(); itX++) {
        std::vector<int>::const_iterator itRightT{}; // Iterator of right T position. 
        itRightT = itX + 4;
        if (itRightT != entries.end()) {
            if (*itX <= *itRightT) {
                tempEntries.push_back(*itX);
            }
        }
        else {
            break;
        }
    }

    for (std::vector<int>::const_reverse_iterator itReverseX = entries.rbegin();
        itReverseX != entries.rend(); itReverseX++) {
        std::vector<int>::const_reverse_iterator itLeftT{}; // Iterator of left T position.
        itLeftT = itReverseX + 3;
        if (itLeftT != entries.rend()) {
            if (*itReverseX <= *itLeftT) {
                tempEntries.push_back(*itReverseX);
            }
        }
        else {
            break;
        }
    }

    std::sort(tempEntries.begin(), tempEntries.end());

    for (std::vector<int>::iterator it = simEntries.begin();
        it != simEntries.end(); it++) {
        if (std::find(tempEntries.begin(), tempEntries.end(), *it) != tempEntries.end()) {
            *it = 0;
        }
    }

    // Desired Result: 1, 0, 0, 5, 0, 0, 0, 3, 3, 0
    //  Actual Result: 1, 0, 0, 5, 0, 0, 0, 0, 0, 0
    return simEntries; 
}

#ifndef RunTests
int main()
{
    std::vector<int> result = simulate({ 1, 2, 0, 5, 0, 2, 4, 3, 3, 3 });
    for (int value : result)
    {
        std::cout << value << " ";
    }
    // Expected output
    // 1, 0, 0, 5, 0, 0, 0, 3, 3, 0
}
#endif

我尝试过用std::set_intersection这类STL函数完成元素比较，但它无法直接修改目标容器内的元素，希望能得到解决该问题的帮助。
