Finally I was able to get my code to work.
I am pasting the code.
Two changes I made :
1. I removed the cin.sync();
2. I added cin.ignore() before the for loop for reading the matrix (using
getline())
Required because the newline after the reading of C and N was being
treated as a single line.
--------------------------------
#include <iostream>
#include <vector>
#include <sstream>
#include <string>
#include <ios>
#include <limits>
using namespace std;
int main() {
int C;
cin >> C;
for (int caseno = 1; caseno <= C; caseno++) {
int N; cin >> N;
int tracesum=0;
string numbers;
int intnumbers;
vector<bool> rowsrepeat;
vector<bool> colsrepeat;
vector<bool> arrelementrowcount1;
vector <vector<bool> > arrelementrowcount2;
vector<bool> arrelementcolcount1;
vector <vector<bool> > arrelementcolcount2;
int rowsrepeatnum=0;
int colsrepeatnum=0;
for (int i=0; i<N; i++) {
rowsrepeat.push_back(false);
colsrepeat.push_back(false);
}
for (int i=0; i<=N; i++) {
arrelementrowcount1.push_back(false);
}
for (int i=0; i<N; i++) {
arrelementrowcount2.push_back(arrelementrowcount1);
}
for (int i=0; i<=N; i++) {
arrelementcolcount1.push_back(false);
}
for (int i=0; i<N; i++) {
arrelementcolcount2.push_back(arrelementcolcount1);
}
vector<int> arrinput1;
vector <vector<int> > arrinput2;
cin.ignore();
for (int i=0; i<N; i++) {
arrinput1.clear();
getline(cin, numbers);
istringstream ss(numbers);
while (ss >> intnumbers) {
arrinput1.push_back(intnumbers);
}
arrinput2.push_back(arrinput1);
}
int i=0;int j=0;
for (auto it1 = arrinput2.begin(); it1 != arrinput2.end(); it1++) {
j=0;
for (auto it2 = (*it1).begin(); it2 != (*it1).end(); it2++ ) {
int in = *it2;
if (arrelementrowcount2[i][in]) {
rowsrepeat[i] = true;
}
arrelementrowcount2[i][in] = true;
if (arrelementcolcount2[j][in]) {
colsrepeat[j] = true;
}
arrelementcolcount2[j][in] = true;
if (i==j) {
tracesum = tracesum + in;
}
j++;
}
i++;
}
for (int i=0; i<N; i++) {
if (rowsrepeat[i]) rowsrepeatnum++;
if (colsrepeat[i]) colsrepeatnum++;
}
cout << "Case #" << caseno << ":" << " " << tracesum << " " <<
rowsrepeatnum << " " << colsrepeatnum << endl;
}
}
