I did one solution with unordered_map which makes the code a bit simple-

bool isValid(string s) {
stack<char> st;
unordered_map<char, char> mp = {{'(', ')'}, {'{', '}'}, {'[', ']'}};
for(char c: s) {
if(mp.find(c) != mp.end()) {
st.push(c);
} else if(!st.empty() && mp[st.top()] == c) {
st.pop();
} else {
return false;
}
}

return st.empty();
}
