Add Average to Score Values

Given a string that may contain one or more occurrences of a JSON-like substring in the format "score": [a, b, c], where a, b, and c are integers, your task is to compute the average of these three numbers and append the average to the list. The average is computed as \(\frac{a+b+c}{3}\) and should be printed with one decimal place.

If no such substring exists, output the string unchanged.

Input is read from stdin and output is produced to stdout.

inputFormat

A single line containing the string to process.

outputFormat

Output the modified string after appending the average to each found "score" array. If no such array exists, print the original string.## sample

"score": [2, 3, 4]

"score": [2, 3, 4, 3.0]
