Finding lowest non-zero number in an array

Post icon  Posted 07 January 2010 - 08:53 AM

Hey guys, hope you all had a good Christmas and new year :)

I have a quick (probably easy) question about reading values in an array...I've been working on a program for 6 hours today and my brain has suddenly deserted me :)

I want to basically print/select the lowest number in an array, which is non-zero.

For example if the array was:

X[5]

and the elements were:

[0 0 3 4 5]


I would like it to select the minimum (3 in this case) and enter it into (for example) minX.

Thanks B)

Sort the array, then scan it for first element > 0

My brain having not done anything productive this morning started to come up with a horrible solution.

You don't even have to sort it...

int minX = Integer.MAX_VALUE;

for (int i = 0; i < X.length; i++)
{
    if (X[i] != 0 && X[i] < minX)
        minX = X[i];
}
