Practice Transpose File
Read the task, work through the examples, and check your approach against the constraints. Use the original LeetCode task for coding and submissions.
Problem Statement
Read file.txt and transpose its space-separated table: each original column becomes an output row, retaining the original order of cells. Every input row has the same number of columns. Practice approach: In awk, accumulate one output string per column while reading rows, inserting spaces between cells. Print those strings in numeric column order at the end. Do not rely on hash-map iteration order. A rectangular two-row, three-column example exposes accidental assumptions that the input is square.
