Answer:
Below is the Python code with suitable comments.
Explanation:
#Input file name acquisition
filename=input('Enter the input file name: ')
#Opening the input file
inputFile = open(filename,"r+")
#Dictionary definition.
list={}
#Read and split file content using a loop
for word in inputFile.read().split():
#Check if the word exists in the file.
if word not in list:
list[word] = 1
#Increment count by 1
else:
list[word] += 1
#Closing the file.
inputFile.close();
#Output a blank line
print();
#Sorting words according to their ASCII values.
for i in sorted(list):
#Display unique words along with their
#frequencies in alphabetical order.
print("{0} {1} ".format(i, list[i]));
public static int factorial(int n) {
if (n >= 1 && n <=12) {
if (n == 1)
return 1;
else
return n * factorial(n - 1);
}
else
return -1;
}
Explanation: The factorial method takes a single integer n as input. It checks if n is within the range of 1 to 12. If it is, it further checks if n equals 1. If it is indeed 1, it returns 1 as the factorial. Otherwise, it recursively calls itself with n decreased by 1, multiplying the result by n. If n is outside this range, the method returns -1 indicating the input is invalid.
Option (d) is the correct choice. A data warehouse serves as a storage system that contains gathered information and data for informed decision-making via analysis. The information in a data warehouse is organized by subject and includes historical data along with sources to provide clarity. The other options are incorrect as they suggest that data is encoded differently, retrieved for limited times, updated in real-time, or structured hierarchically.
