Detailed explanation-1: -In computer science, a string refers to any finite sequence of characters. These characters can be letters, numbers, punctuation marks, symbols, etc. A string is most commonly defined in terms of its length, i.e. the number of characters it is made up of.
Detailed explanation-2: -We are provided with a string of letters and numbers and we are asked which letters and numbers are identical to the string provided. The correct answer will be the first one.
Detailed explanation-3: -Separators are Java’s punctuation. Just as periods, semicolons, question marks, pairs of parenthesis, and other punctuation add structure to written text, Java separators help the Java compiler interpret components of Java source code.
Detailed explanation-4: -isalnum() is a built-in Python function that checks whether all characters in a string are alphanumeric. In other words, isalnum() checks whether a string contains only letters or numbers or both. If all characters are alphanumeric, isalnum() returns the value True; otherwise, the method returns the value False .
