Pangram Checker

Given a sentence, determine whether it is a pangram. A pangram is a sentence that contains every single letter of the English alphabet at least once. In other words, the sentence must include all the letters from \(a\) to \(z\) (case-insensitively). For example, "The quick brown fox jumps over the lazy dog" is a pangram, while "Hello World" is not.

Your task is to read a sentence from the standard input and output True if the sentence is a pangram, and False otherwise.
