INTERNOA
See Roblox online assessment and hiring insights
You are given a list of strings data, where each string is in the form
"$device_id, $usage_in_minutes", such that $device_id contains
exactly five lowercase English letters ('a'-'z') and $usage_in_minutes contains
exactly four digits, representing a positive integer between 1 and 1440 (possibly with leading zeros).
For instance, "abxyz, 0010" describes $device_id = "abxyz" and
$usage_in_minutes = 10 minutes.
Given data, your task is to return the $device_id with the largest
value of $usage_in_minutes. You may assume that all values of $device_id and
$usage_in_minutes are both pairwise distinct in data.
