Explanation / Answer
puts "Enter string1 : "
str1 = gets.chomp
puts "Entered string : " , str1
puts "Length of string :" , str1.length
puts "Reverse of entered string", str1.reverse
puts "No.of words in string", str1.split(' ').length
puts "Enter string 2 : "
str2 = gets.chomp
puts "is two strings equal", str1 == str2
puts "string 1 is polindrom or not : ", str1.reverse == str1
puts "5 characters substring", str1[1..5]
puts "Revers of first string : ", str1.reverse
puts "Uppercase of first string : ", str1.upcase
puts "Lowercase of second string :", str2.downcase
