println(output)Option 1: Using a Dictionary
In this solution, we use a dictionary to store the counts of each word in the input string. We split the input string into individual words, convert them to lowercase, and then loop through each word. If the word is already in the dictionary, we increment its count by 1. If it is not in the dictionary, we add it with a count of 1. Finally, we sort the dictionary by the counts in descending order and create a string to store the output. We loop through each word-count pair in the sorted dictionary and add them to the output string.
Option 2: Using a Counter
In this solution, we use the Counter class from the Julia standard library to count the occurrences of each word in the input string. We split the input string into individual words, convert them to lowercase, and then create a Counter object from the list of words. Finally, we use the most_common() method of the Counter object to get a list of word-count pairs in descending order and create a string to store the output.
using Counter
function solve_question(input::String)
# Split the input string into individual words
words = split(input)
# Create a Counter object from the list of words
word_counts = Counter(words)
# Get a list of word-count pairs in descending order
sorted_counts = most_common(word_counts)
# Create a string to store the output
output = ""
# Loop through each word-count pair in the sorted list
for pair in sorted_counts
# Add the word and count to the output string
output *= pair[1] * ": " * string(pair[2]) * "n"
end
return output
end
input = "What python creator guido van rossum thinks of rust go julia and typescript"
output = solve_question(input)
println(output)Option 3: Using a DataFrame
In this solution, we use the DataFrame package to count the occurrences of each word in the input string. We split the input string into individual words, convert them to lowercase, and then create a DataFrame object from the list of words. Finally, we group the DataFrame by the words and count the occurrences of each word, sort the DataFrame by the counts in descending order, and create a string to store the output.
using DataFrames
function solve_question(input::String)
# Split the input string into individual words
words = split(input)
# Convert the list of words to a DataFrame
df = DataFrame(words=words)
# Group the DataFrame by the words and count the occurrences
word_counts = combine(groupby(df, :words), nrow)
# Sort the DataFrame by the counts in descending order
sorted_counts = sort!(word_counts, :nrow, rev=true)
# Create a string to store the output
output = ""
# Loop through each row in the sorted DataFrame
for row in eachrow(sorted_counts)
# Add the word and count to the output string
output *= row.words * ": " * string(row.nrow) * "n"
end
return output
end
input = "What python creator guido van rossum thinks of rust go julia and typescript"
output = solve_question(input)
println(output)Option 2: Using a Counter is the best option for solving this Julia question. It provides a concise and efficient way to count the occurrences of each word in the input string. The Counter class from the Julia standard library is specifically designed for this purpose and simplifies the code compared to using a dictionary or a DataFrame.
