hey guys i have a problem with my array : IndexOutOfRangeException: Array index is out of range.

i Defined int tuss_array[]=new int[24] how can i fix it?

here is my code:

 //provide random number
 void RandomTuss(){
     
             tuss1 = Random.Range (tussmin1, tussmax1);
             tuss2 = Random.Range (tussmin2, tussmax2);
     
             tuss_result= "TuSS1:"+tuss1.ToString () + "TuSS2:"+tuss2.ToString ();
     
             if (tuss1 == tuss2) 
             {
                 Debug.Log("Great!"+"num of toss1:"+"   "+tuss1+"num of toss2:"+"   "+tuss2);
             }
     
             Debug.Log (" toss1 is:"+"   " +  tuss1+ " toss2 is:"+"   " + tuss2 );
         
     
         //Checking tuss1 and tuss2 then make a decision x coin should move
     
             for (int i = 0; i <tuss_array.Length; i++) {
     
                 if(tuss_array[i]>0)
                 {
                     int tuss_pair=i-tuss1+tuss2;
                     int white_Coin_Tuss1=i-tuss1;
                     int white_Coin_Tuss2=i-tuss2;
                     int white_Coin_TussPair=i-tuss_pair;
                 
     
                     
     
     
     
                     if(tuss_array[white_Coin_Tuss1] > -2);
                     {
                             Debug.Log (" the white Coins should move to these points(tuss1):  " + white_Coin_Tuss1.ToString());
                     }
                     if(tuss_array[white_Coin_Tuss2] > -2);
                     {
                         Debug.Log (" the white Coins  should move to these points(tuss2):  " + white_Coin_Tuss2.ToString());
                     }
                     if(tuss_array[tuss_pair] > -2 );
                     {
                         Debug.Log (" the white Coins can should to these points(Pair):  " + tuss_pair.ToString());
                     }
                 
                     }
     
                 }
         }
