What is a pangram in Java programming ?

A pangram is a sentence that contains every letter of the alphabet at least once. The most famous example of a pangram in English is: "The quick brown fox jumps over the lazy dog." This sentence includes every letter from 'a' to 'z'. Pangrams are often used in typography and font testing because they showcase all the letters in a given typeface. Why Check for Pangrams? Checking for pangrams can be useful in various applications, such as: Font Testing: Ensuring that a font displays all characters correctly. Keyboard Layout Testing: Verifying that all keys on a keyboard are functional. Language Processing: Analyzing text for completeness in language models. Pangram Algorithm Build a hash table (boolean vector). To indicate which characters in the string are present. Traverse the entire string of characters that has been provided. Subtract "A" from the uppercase letter if it is located to obtain the index. If the lowercase letter is discovered, take "a" off to discover the index. Mark the vector's value as true (character found). Return false if any character is not marked (a character not found). If not, return true.
