+Question:-
+ Perfect Numbers in range
+
+
+Given two integers a and b, write a program to find and print all perfect numbers in the range from a to b.
+A perfect number is a positive integer that is equal to the sum of its proper divisors (excluding itself).
+
+Note:-
+This is a functional problem. You do not need to take any input. You just need to complete the function, and print the output.
+Input
+First Line will contain an integer a representing the start of the range.
+Second Line will contain an integer b representing the end of the range.
+Output
+Print all perfect numbers between a and b in a space-separated matter.
+Example
+Input
+1
+100
+
+Output
+6 28
