I need some help regarding this question ...

Yes i know that this has been answered but ... i have some issues regarding this where when the user select one of the operation especially 3 and 4 ... the output seems to be wrong and could be some kind of logical error but i just couldnt find it... an explanation in the source code using comment would be greatly appreicated ...

#include #include #include

int main() { set set1, set2;

int m, n, l, k; cout > m; cout > n; cout > l;

cout > k; set1.insert(k); }

cout > k; set2.insert(k); }

cout map; for (int i = 1; i > k1 >> k2; map[k1] = k2; }

for (int p = 0; p > ch;

if (ch == 1) { cout v1(set1.begin(), set1.end()), v2(set2.begin(), set2.end()); set inter;

sort(v1.begin(), v1.end()); sort(v2.begin(), v2.end());

for (int i = 0, j = 0; i v2[j]) j++; }

for (auto it = inter.begin(); it != inter.end(); it++) cout

else if (ch == 2) { cout Union; for (auto it = set1.begin(); it != set1.end(); it++) Union.insert(*it); for (auto it = set2.begin(); it != set2.end(); it++) Union.insert(*it);

for (auto it = Union.begin(); it != Union.end(); it++) cout

else if (ch == 3) { cout

int s{}; for (auto i : map) { int a = i.first, b = i.second, s = 0; for (auto j : map) {

if (j.first == b) { s = 1; break; } } if (s == 0) break; }

if (s == 0) cout

else if (ch == 4) { cout

if (s == 0) cout

return 0; }

the output using the same sample from the question :
