860. Lemonade Change
原本想蝦雞巴亂寫很複雜的程式碼，後來想想還是簡單比較好
class Solution {
public:
bool lemonadeChange(vector<int>& bills) {
int bill5 = 0;
int bill10 = 0;
// int bill20 = 0;
for(int bill : bills) {
int change = bill - 5;
if(change == 0) {
bill5++;
} else if(change == 5) {
if(bill5 ==0) {
return false;
}
bill5--;
bill10++;
} else if(change == 15) {
if(bill10 >= 1 && bill5 >=1) {
// bill20++;
bill5--;
bill10--;
} else if( bill5 >=3) {
// bill20++;
bill5 -= 3;
} else {
return false;
}
}
}
return true;
}
};
