Problem Statement
Alex works at a clothing store. There is a large pile of socks that must be paired by color for sale. Given an array of integers representing the color of each
sock, determine how many pairs of socks with matching colors there are.
For example, there are n=7 socks with colors ar = (1,2,1,2,1,3,2). There is one pair of color 1 and one of color 2. There are three odd socks left, one of each
color. The number of pairs is 2.
Function Description
A
Complete the sockMerchant function in the editor below. It must return an integer representing the number of matching pairs of socks that are available.
sockMerchant has the following parameter(s):
n: the number of socks in the pile
ar: the colors of each sock
Input Format
The first line contains an integer n, the number of socks represented in ar.
The second line contains n space-separated integers describing the colors ar[i] of the socks in the pile.
Constraints
1
<= n <= 100
1 <= ar[i] <= 100 & 0 <=i<n
Output Format
Return the total number of matching pairs of socks that Alex can sell.

The signature of this function should be: bool word_diff(std::string word1, std::string word2); For example: std::string str1 = "Hello World";std::string str2 = "hEllO World";std::string str3 = "World";std::string str4 = "Hello World";bool result = word_diff(str1, str2); // Falsebool result = word_diff(str1, str3); // Falsebool result = word_diff(str1, str4); // True 2. Now let’s follow a classical approach to compare the content of 2 files. We should open each file, read their content word by word and compare them until a first mismatch occurs.Let’s implement a function called classical_file_diff that takes 2 arguments each of which is a file name and returns a boolean indicating whether the 2 files are identical or not.
