Re: [閒聊] 每日leetcode

[Wardyal (Wardyal)]

※ 引述《dont (dont)》之銘言：

我寫了100多行

int find_same_char(string str);
void set_number_sets(number_set *ns, string str);

int calculate_gcd(int a, int b);
int calculate_lcm(int a, int b);

number_set calculate_fraction(number_set ns1, number_set ns2);
number_set fraction_reduction(number_set ns);
string get_number_set_output(number_set ns)

搞了7個子函式

=====

class Solution {
public:
    string fractionAddition(string expression) {
        stringstream ss(expression);
        char op;
        int a,b,c,d;
        int num,den;
        ss>>a;ss>>op;ss>>b; //extracting the 1st 2 numbers
        while(ss>>c) //til we have the number
        {
            ss>>op; // op is the operator. which is '/' in our case
            ss>>d;
            num= a*d + b*c;
            den= b*d;
            a= num/__gcd(abs(num),abs(den));
            b= den/__gcd(abs(num),abs(den));
        }
        c=__gcd(abs(a),abs(b));
        a=a/c;
        b=b/c;
        return to_string(a)+'/'+to_string(b);
    }
};

結果看了一下解答

靠北 他怎麼20幾行就寫完了

還有ss又是什麼鬼 絲絲蛇嗎
