There are “two ways” where you can fill the necessary symbol.
Method 1:
if(x>17): This will check whether the given value of ‘x’ is greater than 17. Suppose if you want to include 17 also then you must write if(x>=17).
Method 2:
if(!(x<17)): This conditional statement checks whether the value of x is not less than 15. We use both “comparison operator” and a “not operator” to achieve the given statement through programming constructs.
Here the trick is that, we place a false statement (x<17) and then invert that value to get the desired condition.
Since the web server is hosts a lot of internet facing websites .On investigation it was find out that the web server is getting flooded with a lot of ping requests hence it becomes unavailable occasionally. So to tackle this problem we should block all of the incoming ICMP requests.
