Can anyone help me with my code??? I have used the same logic in my code.
#include
#include
#include
using namespace std;
int main() {
// your code goes here
int t; cin >> t;
while (tā) {
int ip1[3]; int ip2[3];
// p, q, r
for (int i = 0; i < 3; i++) {
cin >> ip1[i];
}
// a, b, c
for (int i = 0; i < 3; i++) {
cin >> ip2[i];
}
// differences
int d = 0;
set<int> diff;
vector<int> v;
for (int i = 0; i < 3; i++) {
if (ip1[i] != ip2[i]) {
d++;
diff.insert(ip2[i] - ip1[i]);
v.push_back(i);
}
}
if (d == 0)
cout << 0 << endl;
else if (d == 1)
cout << 1 << endl;
else if (d == 2) {
if (diff.size() == 1)
cout << 1 << endl;
else {
int p = ip1[v[0]], a = ip2[v[0]], q = ip1[v[1]], b = ip2[v[1]];
if (p != 0 && q != 0 && a%p == 0 && b%q == 0 && a/p == b/q)
cout << 1 << endl;
else
cout << 2 << endl;
}
}
else if (d == 3) {
int p = ip1[0], q = ip1[1], r = ip1[2], a = ip2[0], b = ip2[1], c = ip2[2];
bool cond1, cond2, cond3;
cond1 = (p != 0 && q != 0 && a%p == 0 && b%q == 0 && b/q == a/p);
cond2 = (q != 0 && r != 0 && b%q == 0 && c%r == 0 && c/r == b/q);
cond3 = (r != 0 && p != 0 && c%r == 0 && a%p == 0 && a/p == c/r);
if (diff.size() == 1)
cout << 1 << endl;
else if (p != 0 && q != 0 && r != 0 && a%p == 0 && b%q == 0 && c%r == 0 && a/p == b/q && b/q == c/r)
cout << 1 << endl;
else {
if (diff.size() == 2)
cout << 2 << endl;
else if (cond1 || cond2 || cond3)
cout << 2 << endl;
else {
int d1 = (b - a), d2 = (q - p), d3 = (c - b), d4 = (r - q);
if (d2 != 0 && d4 != 0 && d1%d2 == 0 && d3%d4 == 0 && d1/d2 == d3/d4)
cout << 2 << endl;
else
cout << 3 << endl;
}
}
}
}
return 0;
}
I also got the logic adding one by one edge cases but canāt get AC.
my code is working fine on compiler but while submitting gives runtime error.
idk why??
any help is much appreciated.
here is my code >>>

make sure to not divide by 0 at any instance.

runtime error means somewhere u r doing division by 0,check that
and for wa ig
check the case
-10 2 -1
3 3 2
ans-2

I checked division by zero for each case and for your given test case its giving 2.
I have tried several such possibilities.
Yeah i have checked division by zero for every single caseā¦and i didnāt find anything new in editorial thats not in my code.
