   49   36   55   67

(2) Search and display largest integer: 97

(3) Search and display all odd integers:
   23   51   19   35   49   81   97   45   73   49   55   67

(4) Display all integers within user designated range
Please input the lower end of the range: 20
Please input the upper end of the range: 50
