System.out.println("Enter the limit of the fibonacci series:");
int userInput = sc.nextInt();
int variable1=1;
int variable2=0;
int fibonacciResult=0;
System.out.println("Finally the fibonacci series is:");
for (int point=0; point<=userInput;point++) {
System.out.print(fibonacciResult+" ");
fibonacciResult=variable1+variable2;
variable1=variable2;
variable2=fibonacciResult;
}
}
}
