和为S的连续数列

输入一个正数target，打印出所有和为target的连续正数序列（至少含有两个数）。例如输入15，由于1＋2＋3＋4＋5＝4＋5＋6＝7＋8＝15，所以结果打印出3个连续序列1～5、4～6和7～8>

#include <iostream>
using namespace std;


void PrintNumber(int small, int big){
    for (int i = small; i <= big; i++){
        cout << i << " , ";
    }
}

void FindContinuousSequence(int sum){
    int small = 1;
    int big = 2;
    int middle = (sum + 1) / 2;
    int currentSum = small + big;

    if (sum < 3){
        return;
    }

    while (small < middle){
        if (currentSum == sum)
        {
            PrintNumber(small , big);
        }
        while(currentSum > sum && small < middle){
            currentSum -= small;
            small ++;
            if (currentSum == sum)
                PrintNumber(small , big);
        }
        big ++;
        currentSum += big;
    }
}

int main(){
    int sum = 5;
    FindContinuousSequence(sum);
}
