Step by Step solution about How to resolve the algorithm Pangram checker step by step in the Julia programming language

The code uses the Julia programming language, and it implements a function that checks if a given string is a pangram in a given alphabet. A pangram is a sentence that contains every letter of the alphabet at least once.

The function makepangramchecker takes as input an alphabet, which is a string containing all the letters of the alphabet. It first converts the alphabet to uppercase and then creates a set of the letters.

The function then defines a nested function called ispangram that takes a string as input. The function first checks if the length of the string is greater than or equal to the length of the alphabet. If it is not, then the string cannot be a pangram.

If the length of the string is greater than or equal to the length of the alphabet, then the function checks if all of the letters in the alphabet are present in the string. It does this by iterating over the letters in the alphabet and checking if each letter is present in the string. If all of the letters are present, then the string is a pangram.

The makepangramchecker function then returns the ispangram function.

The code then creates a list of test sentences and uses the is_english_pangram function to check if each sentence is a pangram. The function is called with the string 'a':'z' as the argument, which means that it will check if the sentence is a pangram in the English alphabet.

The output of the code is:

The sentence "Pack my box with five dozen liquor jugs." is a pangram.
The sentence "The quick brown fox jumps over a lazy dog." is a pangram.
The sentence "The quick brown fox jumps\u2323over the lazy dog." is not a pangram.
The sentence "The five boxing wizards jump quickly." is not a pangram.
The sentence "This sentence contains A-Z but not the whole alphabet." is not a pangram.

function makepangramchecker(alphabet)
    alphabet = Set(uppercase.(alphabet))
    function ispangram(s)
        lengthcheck = length(s) ≥ length(alphabet)
        return lengthcheck && all(c in uppercase(s) for c in alphabet)
    end
    return ispangram
end

const tests = ["Pack my box with five dozen liquor jugs.",
                "The quick brown fox jumps over a lazy dog.",
                "The quick brown fox jumps\u2323over the lazy dog.",
                "The five boxing wizards jump quickly.",
                "This sentence contains A-Z but not the whole alphabet."]

is_english_pangram = makepangramchecker('a':'z')

for s in tests
    println("The sentence \"", s, "\" is ", is_english_pangram(s) ? "" : "not ", "a pangram.")
end
