LeetCode_ 20 (brackets match)

Title Description ： Given one only includes ‘(’,‘)’,‘{’,‘}’,‘[’,‘]’ String s , Determines whether the string is valid .

Valid string needs to meet ：
1、 Opening parentheses must be closed with closing parentheses of the same type .
2、 The left parenthesis must be closed in the correct order .

Example 1：
Input ：s = “()”
Output ：true

Example 2：
Input ：s = “()[]{}”
Output ：true

Example 3：
Input ：s = “(]”
Output ：false

Example 4：
Input ：s = “([)]”
Output ：false

Example 5：
Input ：s = “{[]}”
Output ：true

Tips ：

1 <= s.length <= 104
s Brackets only ‘()[]{}’ form

class Solution {
    
    public boolean isValid(String s) {
    
        int length=s.length()/2;
        for(int i=0;i<length;i++){
    
        	// Will encounter （） or 【】 or {
    } Eliminate it all like music 
            s=s.replace("()","").replace("[]","").replace("{}","");
        }
        return s.length()==0;
    }
}
