How can I give input to a program using STDIN
Suppose I want the program to take the value x=10
On some other site i found it as STDIN.read,but its not working.

print("Give me a string ");
STDOUT.flush
a_string = gets
print(“You gave me ‘#{a_string}’”)

Please check http://codegolf.com/reverse where we need to input using
STDIN
You don’t seem to have used STDIN
gets works on the standard input if you insist you can write
STDIN.gets if that makes you feel better

STDIN.public_methods.sort
=> [“<<”, “==”, “===”, “=~”, “id”, “send”, “all?”, “any?”,
“binmode”, “class”, “clone”, “close”, “close_read”, “close_write”,
“closed?”, “collect”, “detect”, “display”, “dup”, “each”, “each_byte”,
“each_line”, “each_with_index”, “entries”, “eof”, “eof?”, “eql?”,
“equal?”, “extend”, “fcntl”, “fileno”, “find”, “find_all”, “flush”,
“freeze”, “frozen?”, “fsync”, “getc”, “gets”,
^^^^^^ here is your gets
