Two sibling inputs must stay in sync — so state lives in the parent. Input: events left V or right V (one per line) each setting the shared value. Print the value BOTH siblings display after all events, as left=V right=V.
Input: event lines.
Output: one line: left=V right=V.
Your program reads from stdin and prints to stdout.
Example 1
Input: left 5 right 9
Output: left=9 right=9
