Thread: Array container is not enough to hold all needed values

this program finds fibonacci sequence starting at 1 then separate the 2 digit numbers so that it's not too big then factorial the numbers and add them. my problem is that its missing the final value in the sequence because the array is not big enough.

int sum = 1;
    int input;
 
    System.out.print("Enter a number: ");
    input = console.nextInt();
 
    int[] fib = new int[input];
    int[] out = new int[input];
    int[] fib2 = new int[input];
 
    fib[0] = 0;
    fib[1] = 1;
 
    fib2[0] = 0;
    fib2[1] = 1;
    if (input > 0) {
 
        if (input <= 7) { // for numbers 1,1,2,3,5,8 
            for (int i = 2; i < input; i++) {
                fib[i] = fib[i - 1] + fib[i - 2];
                out[i] = factorial(fib[i]);
 
            }
        } else { // this is for the 2 digit numbers 13,21,34,55,89
            for (int i = 2; i < input; i++) {
                fib[i] = fib[i - 1] + fib[i - 2];
                fib2[i] = fib2[i - 1] + fib2[i - 2];
            }
            for (int i = 2; i < input; i++) {
                fib[i] = separate(fib[i]);
                fib2[i] = separate2(fib2[i]);
                out[i] = factorial(fib[i]) + factorial(fib2[i]);
            }
 
        }
 
        for (int i : out) {
            sum = sum + i;
        }
        System.out.println(sum);

output is 40,490 but it should be 40,730 all is working except that if I input 10 it's missing the final value 55. computation is like this 1!+1!+2!+3!+5!+8!+1!+3!+2!+1!+3!+4!+5!+5! = 40,730

if for example the user input 10 first the program would calculate the first 10 fibonacci sequence 1,1,2,3,5,8,13,21,34,55 then it will separate the 2 digit numbers into 1 digit numbers so its not too big when we factorial it so the actual value is 1,1,2,3,5,8,1,3,2,1,3,4,5,5 the we factorial each 1!,1!,2!,3!,5!,8!,1!,3!,2!,1!,3!,4!,5!,5! then we add its results 1!+1!+2!+3!+5!+8!+1!+3!+2!+1!+3!+4!+5!+5! = 40,730, but my program does not include the last 5!+5! into the array so the result is only 40,490 instead of 40,730

you mean like this ?

input = console.nextInt() + 1;

that would make the

if (input <= 7)

wrong and the else statement right

sorry but what do you mean compute value of extra? i can't visualize what your saying , can you show me?
