Question

Why my code doesn't work? Test #3 - fail

It's my code:
https://code.sololearn.com/cjSpSlZkM2qE/#java

Answer 1

We need use .trim() when read line

Answer 2

perhaps the code will look better and more readable.
But code doesn't work on Test case #3.
Where is my mistake?

Answer 3

my code doesnt work on test case #3
why?
Where is my mistake in the code?

Answer 4

class Divisible {
public static void div(int a, String b) {
String[] c = b.split(" ");
int res = 0;
int zero = 0;
for (int i = 0; i < c.length; i++) {
if (Integer.parseInt(c[i]) == 0){
zero= zero + zero;
}
else if (a % Integer.parseInt(c[i]) == 0) {
res++;
}
}
if (res == c.length) {
System.out.println("divisible by all");
} else {
System.out.println("not divisible by all");
}
}
}

IT
STILL
FAIL
TEST #3
!!!

WHY?

I am angry!

Answer 5

Can you explain more about problem description...?

Answer 6

this test case is hidden and I don't know why it is fail =(

Answer 7

What is this code is about?
What is expected output for a sample input?
I think it's a pro-code coach problem.. So we don't know, problem description...
But for any input it will print only else part...

Answer 8

Yes, it is from pro-code coach.

In input we receive number
and String with numbers
We need to check if number divisible by all numbers in string

A = 100;
String = 2 5 10
We split to String array
Then we case string to int
then for loop
if 100%2 == 0 && 100%5==0 && 100%10==0

It will print " else if " part.

I dont understand why test case #3 fail =\

Answer 9

res += res;
} else{
res++;
}
What these statements do?

If it divisible then just increment res by 1. So res++;
There is no need of next else part.
And last res==0 means non divisible. So it should be i equal to c array length.
res==c.length

Answer 10

class Divisible {
public static void div(int a, String b) {
String[] c = b.split(" ");
int res = 0;
for (int i = 0; i < c.length; i++) {
if (a % Integer.parseInt(c[i]) == 0) {
res++;
}
}
if (res == c.length) {
System.out.println("divisible by all");
} else {
System.out.println("not divisible by all");
}
}
}

It still fail on test #3

Answer 11

Put the special case for zero as it is but don't increment res.

Answer 12

Check by increment res, for zero also..
If still no effect, then may be, you are missing any special logic from description... May be, read again..

Answer 13

Task:
Test your number against all of the other numbers that you are given to make sure that it is divisible by them.

Input Format:
Two inputs: an integer value (the number you are testing) and a string of variable length of the integers that you should test against separated by spaces.

Output Format:
A string that says 'divisible by all' or 'not divisible by all'.

Answer 14

Ha ha.. Fine you got it..

Answer 15

For python

number = int(input())
divisible = input()
divisible_list = divisible.split()
x = ["divisible by all" if number % int(each) == 0 else "not divisible by all" for each in divisible_list]
print(x[0])
