algorithm - How to diff/substract two lists in Clojure -


उदाहरण: 

  1 1 3 3 4 4 5 5 6 एल 1 1 3 3 4 5 L2 1 1 4 5 6 Res   
 प्रतिबंध:  
     
  1.  अंतर / घटाव को एल 1 शून्य से तत्वों के "सेट" के रूप में परिभाषित किया गया है  
  2.  एल 2 हमेशा एल 1 और एल 2 के तत्वों में डुप्लिकेट हो सकते हैं  
  3.   
  4.  तत्व प्राथमिकताएं हैं (इंट, स्ट्रिंग) और एक ही प्रकार   
      (clojure.set / difference)  यहां (3) की मदद नहीं करता है ।   
     
     
      (defn diff [s1 s2] (मैपैक (fn [[xn]] ( उदाहरण के लिए, दिए गए  
      (डीईएफटी एल 1 [डीएपी एलए 1] 1 1 1 3 3 4 4 5 5 6]) (def L2 [1 3 3 4 5])   
     तब  
      (diff L1 L2) ; (1 1 4 5 6)

Before changing the state, the state is set to 'separate', but calling attachments () causes the same error to be thrown away. I am using EF 6.
