Example: bracket balance java
class Parser{
static HashMap<Character,Character> bracket_map = new HashMap<>();
static {
bracket_map.put(')', '(');
bracket_map.put('}','{');
bracket_map.put(']','[');
}
boolean isBalanced(String s){
Stack<Character> stack = new Stack<>();
char temp;
for (int i = 0; i < s.length(); i++) {
temp = s.charAt(i);
if(temp == '{' || temp == '[' || temp == '('){
stack.push(temp);
}else {
if(stack.isEmpty() || stack.peek() != bracket_map.get(temp)) return false;
stack.pop();
}
}
return stack.isEmpty();
}
}
