Find all the quadruples [a, b, c, d] where a^3 + b^3 = c^3 + d^3 when 1 <= a, b, c or d <= 10000 [closed]

Answer 1

int Search(){
int MAX = 10000000;
for(int a = 0; a < MAX; a++){
    int a3 = a * a * a;
    if(a3 > MAX) break;
    for(int b = a; b < MAX; b ++){
        int b3 = b * b * b;
        if(a3 + b3 > MAX)break;             
        for(int c = 0; c < a; c++){
            int c3 = c*c*c;
            int m = a3 - c3; 
            int d = b+1;
            while(true){
                int d3 = d * d * d;
                if(d3-b3 <= m){
                    if((d3 - b3) == m){
                        count++;
                        PUSH_Modified(a3, b3, c3, b3, a, b, c, d);
                    }
                    d++;
                    continue;
                }
                else
                    break;
            }
        }
    }
