Sensor Filter Selection

#include <iostream>
#include <string>
using namespace std;

enum FilterMode {
    NONE,
    LOW,
    HIGH
};
// Write your enum and function here
int filterSensor(int raw, FilterMode mode = NONE){
    switch(mode){
        case LOW:
            return raw/2;
        case HIGH:
            return raw/4;
        case NONE:
        default:
            return raw;
    }
}
int main() {
    int raw, modeFlag;
    cin >> raw >> modeFlag;

    if (modeFlag == 0) {
        cout << filterSensor(raw);
    } else {
        string filterName;
        cin >> filterName;

        FilterMode filter;

        if (filterName == "LOW") {
            filter = LOW;
        } else {
            filter = HIGH;
        }

        cout << filterSensor(raw, filter);
    }
