//Alternate Series Sum Problem

int n = 7;
float result = 0;

for(float i = 0; i <= n ; i++)

if(i % 2 == 0)

{
result -= 1/i;
}
else
{

result += 1/i;
}

System.out.println(result);

}
}

Answer 1

When i=0 the output is -1/0 = -Infinity. Maybe you should start from i=1.

Answer 2

Yeah, as @dimitris kapoulas pointed out that's fine because you are actually dividing by zero.

Just make sure you don't (if you were using an Integer index it would have thrown an error).
