You have 3 identical prizes to giva away and a pool of 30 finalist. The finalists are assigned numbers of 1 to 30. write a program to randomly select the numbers of 3 finalist to recieve a prize. make sure not to pick the same number twice. For example picking finalist 3, 15, 29 woul valid but picking 3,3,31 would be invalid because finalist number 3 is listed twice and 31 is not a valid finalist number. the following line of code can be used to generate a random number between 1 and 30 int num = ( int) ( mat.random()*30)+1;
