The purpose of an expert system is to capture best practice solutions and program them into a set of rules in a software program. Expert systems are computers that use artificial intelligence technologies to simulate a behavior of a human or another subject.
The knowledge about a specific subject is transformed with this system into a software code.
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;
}
Answer:
is a generic description for how computers use multiple layers of protocol rules to communicate across a network.
Explanation:
OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;
1. Physical Layer.
2. Data link Layer.
3. Network Layer.
4. Transport Layer.
5. Session Layer.
6. Presentation Layer.
7. Application Layer.
Hence, the Open Systems Interconnection (OSI) Reference Model is a generic description for how computers use multiple layers of protocol rules to communicate across a network.
Additionally, each layer has its unique functionality which is responsible for the proper functioning of the communication services.
Answer: A :is concerned with defending users’ freedom of use
C:makes source code available for editing
Explanation:
<span>The answer is RAM. Chat messages are most likely to be found in the RAM of the computer. It is Random Access Memory. </span><span>RAM is considered volatile memory, which means that the stored information is lost when there is no more power.</span>
