# Any wrong with my Java solution?

• following is my java code; it gives the correct answer in my PC, which is 6; but the submission gives 1; any wrong with my solution? or the java test case is broken?

``````public int guessNumber(int n) {
int i = 1;
int j = n;
while (i <= j) {
int k = i + (j - i) / 2;
int r = guess(k);
if (r == 0) {
return k;
}

if (r < 0) {
i = k + 1;
} else {
j = k - 1;
}
}

return i;
}

private int guess(int k) {
return k - 6;
}
``````

• Why did you implement `guess(int)` function?

• @jedihy it is for testing only, will not submit;
and I know what is wrong here,

``````-1 : My number is lower
1 : My number is higher
0 : Congrats! You got it!
``````

I misunderstand "my number" as the number I am guessing, but it should be the given number;

• ``````public int guessNumber(int n) {
int i = 1;
int j = n;
while (i <= j) {
int k = i + (j - i) / 2;
int r = guess(k);
if (r == 0) {
return k;
}

if (r > 0) {
i = k + 1;
} else {
j = k - 1;
}
}

return i;
}
```

the accepted solution;``````

Agree, this is a bit confusing at first glance.
