You are given data in a tabular format. The data contains rows, and each row contains space separated elements.
You can imagine the items to be different attributes, (like height, weight, energy, etc.) and each of the rows as an instance or a sample.
Your task is to sort the table on the th attribute and print the final resulting table.
Note: If two attributes are the same for different rows, print the row that appeared first in the input.
Input Format
The first line contains and separated by a space.
The next lines each contain elements.
The last line contains .
The next lines each contain elements.
The last line contains .
Output Format
Print the lines of the sorted table. Each line should contain the space separated elements. Check the sample below for clarity.
