Leetcode 359) Logger Rate Limiter

22 Nov 2021 in Algorithms

My Solution

class Logger {
    Map<String, Integer> m;
    public Logger() {
        m = new HashMap<>();
    }
    
    public boolean shouldPrintMessage(int timestamp, String message) {
        if(m.containsKey(message)){
            if(timestamp-m.get(message)<10){                
                return false;
            }
        }
        m.put(message,timestamp);
        return true;
    }
}

/**
 * Your Logger object will be instantiated and called as such:
 * Logger obj = new Logger();
 * boolean param_1 = obj.shouldPrintMessage(timestamp,message);
 */

Other Solution

class Logger {
    HashMap<String, Integer> map;
    public Logger() {
        map = new HashMap<>();
    }

    public boolean shouldPrintMessage(int timestamp, String message) {
        if (!map.containsKey(message)) {
            map.put(message, timestamp);
            return true;
        }

        int ts = map.get(message);
        if (timestamp < ts+10) return false;
        map.put(message,timestamp);
        return true;
    }
}
