Program 25 An Encoded Text can be decoded by finding the actual character for the given ASCII Code in
the encoded message.
Write a program to input an encoded text having only a sequence of ASCII values without
any spaces. Any code or value which is not in range (65-90 or 97-122 or 32 for space) will be
ignored and should not appear in the output message. Decode the encoded text and print in
the form of a sentence.
