If I'm assigning here tm(Total max) with Integer.MIN_VALUE then I'm getting output like this -2147483648 . Why i'm getting this?

#1

private int max(Node node) {
int tm = Integer.MIN_VALUE;
for(Node child: node.children) {
int cm = max(child);
if(cm>tm) {
tm = cm;
}
}

	return tm;
}

Hi @LakshmiPrasanna0303

You are getting this because it’s already defined in the library. Integer.MIN_VALUE is the minimum value of integer range which is -(2^31) = -2147483648.

Yes I know that but please check the code I’m checking with the condition (cm>tm) then it should store the maximum value but why it is not going in the loop???

Hi @LakshmiPrasanna0303

This is because for the leaf node or base case, you max function will not run for loop and will directly return tm which will be Integer.MIN_VALUE only and that will be stored in cm.
