Explanation:
Matching parentheses. An math expression may have a number of parentheses like (, ), [, ], { and }. Each openning parenthesis (, or [, or { must be macthed by a corresponding closing parenthsis ), or ] or }. For example, 12 { 34 / [ 6 * ( 55 - 10 ) / ( 100 20 ) ] } has matched pairs of parentheses, while 12 { 34 / ( 6 * ) ] } does not. Write a function to check whether an input math expression has matched parentheses. The header of the function is given as follows:
bool match( const char exp [ ], const int s);
The input math express is store in the char array exp, and the size of exp is s. It returns true if all parentheses are matched or false otherwise.

What is the result of the following code?
x=7//2+10%2**4
print(x)
Answer:
3
Explanation:
We can split the expression into two sections
First Section:
7 // 2 = 3. Using the floor division we only utilize the integer part.
Second Section:
10 % 2**4 = 0**4 = 0
Bringing back the full version expression we have
3 + 0 = 3

Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20.
The program performs the following tasks:
Read the file name of the tsv file from the user.
Open the tsv file and read the student information.
Compute the average exam score of each student.
Assign a letter grade to each student based on the average exam score in the following scale:
A: 90 = < X o
B: 80 = < x < 90
C: 70 = < X < 80
D: 60 = < x < 70
E: X < 60
• Compute the average of each exam.
• Output the last names, first names, exam scores, and letter grades of the students into a text file named report.txt. Output one student per row and separate the values with a tab character.
• Output the average of each exam, with two digits after the decimal point, at the end of report.txt. Hint: Use the setprecision manipulator to format the output.
Ex: If the input of the program is:
StudentInfo.tsv
and the contents of StudentInfo.tsv are: 70 45 59
Barrett Edan 96 97 88
Bradshaw Reagan 73 94 80
Charlton Caius 88 61 36
Mayo Tyrese 90 86 45
the file report txt should contain
Barrett Edan 70 45 59 F
Baadha Boagan 9e 157 89 A
Charlton Caius 73 94 80 B
Mayo and Tyrese 58 61 36 D
Stern and Brenda 90 36 45 C
Average midterm 83.40, midterm2 76.60, final 61.60

You are given an array of integers. Your task is to create pairs of them, such that every created pair has the same sum. This sum is not specified, but the number of created pairs should be the maximum possible. Each array element may belong to one pair only.
Write a function
class Solution public int
solution (int[] A); }
that, given an array A consisting of N integers, returns the maximum possible number of pairs with the same sum.
Examples:
1. Given A = [1, 9, 8, 100, 2], the function should return 2. The pairs are (A[0]. A[1]) and (A[2], A[4]); the sum of each pair is 10.
2. Given A = [2, 2, 2, 3], the function should return 1. Although, for instance, A[0]+A[1] = A[0]+A[2], the pairs (A[0], A[1]) and (A[0], A[2]) cannot exist at the same time, because they both contain a common element, A[0].

please write an Introduction on intrusion detection system and prevention system
PLEASE
Answer:
An Intrusion Detection System (IDS) is a system that monitors network traffic for suspicious activity and issues alerts when such activity is discovered. It is a software application that scans a network or a system for harmful activity or policy breaching. Any malicious venture or violation is normally reported either to an administrator or collected centrally using a security information and event management (SIEM) system. A SIEM system integrates outputs from multiple sources and uses alarm filtering techniques to differentiate malicious activity from false alarms.
