I use prime numbers in code to catalog things with one number. I assign a prime number to a certain characteristic. Then I multiply together the prime numbers for each characteristic contained. Later, that number can be divided a prime number. If a remainder of zero is returned I know it contains the number and what too associate it with.
It sounds like you're using Java, so instead of pseudo-code, I'll give you the actual code. LinkedList<Integer> l; // Let's assume you have a bunch of Integer values in this list. for (int i = 0; i < l.size(); i++){ int n = l.get(i); boolean prime = true; for (int i = 2; i < n; i++){ if (n % i == 0){ prime = false; break; } } if (prime){ l.remove(i); i--; } }
There are several different methods to convert an integer variable to a string variable in Java. For example, one can use the following code to convert an integer variable to a string variable: Integer.toString(number)
see the program
My Code: ======================================… >> disp('input a pair of natural numbers, N and M with M>N'); N=input('N='); M=input('M='); for j=0:(M-N) Prime=1; for i=2:((N+j)/2) if mod((N+j),i)==0 Prime=0; break end end if Prime==1 disp('This is a Prime Number'); else disp('Not Prime'); end end
