The first line gives the number of students n, and each of the next n lines gives "name korean english math". Print a table with five columns NAME, KOR, ENG, MATH, AVG. AVG is the average of the three scores rounded to one decimal place (275 / 3 → 91.7, 171 / 3 → 57.0).
- Each column's width is the length of the longest of its header and all values in that column.
- The first line is the header, the second line joins, for each column, as many "-" as its width with "-+-", and then one line per student (in input order).
- In the header line and the student lines, put " | " (space, vertical bar, space) between columns. The NAME column is left-aligned (spaces after), the other columns are right-aligned (spaces before). The header follows the same rule.
Input
1 ≤ n ≤ 20, a name is 1–15 English letters, 0 ≤ each score ≤ 100
Output
a table of n + 2 lines

First measure each column's width (including the header), then print aligned. Forget the header and NAME overflows its column when every name is short. Setting the width at run time differs by language: Python f"{s:<{w}}"/f"{s:>{w}}", C printf("%-*s", w, s)/"%*s" (pass the width for *), C++ std::left/std::right with std::setw(w), Java String.format("%-" + w + "s", s), JS/TS padEnd/padStart, C# PadRight/PadLeft (C#'s {0,-5} needs a constant width). The average must divide as a real number, like / 3.0. In C, C++, Java and C#, (a + b + c) / 3 is integer division, so 91.7 becomes 91. Craykon aligns with PadRight(width)/PadLeft(width), makes one decimal with Str.Fixed(sum / 3, 1), and builds the dash line with "-".Repeat(w) and Join("-+-").
