True or false? Colons are required when entering the MAC address into the Reservation window?

Computers and Technology
1 answer:
NeX [460]3 years ago
7 0

Answer:

False

Explanation:

A reservation in server-client communication is used to map your NIC’s MAC address to a particular IP address. A reserved MAC address should stay reserved until it gets to a point where a computer needs to get its address from DHCP. It should always remain static. To configure mac address in a DHCP console, you are required to use dashes to separate the MAC values. You can opt not to use dashes if you want to but do not use colons as separators. It will not work and will only populate errors.

which one of the following will reach every element in the array a? 1. for(int i = 0; i <= a.length; i++) 2. for(int i = 0; i
andrey2020 [161]

Answer:

You can simplify the problem down by recognizing that you just need to keep track of the integers you've seen in array that your given. You also need to account for edge cases for when the array is empty or the value you get would be greater than your max allowed value. Finally, you need to ensure O(n) complexity, you can't keep looping for every value you come across. This is where the boolean array comes in handy. See below -

public static int solution(int[] A)

{

int min = 1;

int max = 100000;

boolean[] vals = new boolean[max+1];

if(A.length == 0)

return min;

//mark the vals array with the integers we have seen in the A[]

for(int i = 0; i < A.length; i++)

{

if(A[i] < max + 1)

vals[A[i]] = true;

}

//start at our min val and loop until we come across a value we have not seen in A[]

for (int i = 1; i < max; i++)

{

if(vals[i] && min == i)

min++;

else if(!vals[i])

break;

}

if(min > max)

return max;

return min;

}
