Chapter 10, Problem 3P
The following is an old word puzzle: “Name a common word, besides tremendous, stupendous, and horrendous, that ends in dous.” If you think about this for a while it will probably come to you. However, we can also solve this puzzle by reading a text file of English words and outputting the word if it contains “dous” at the end. The text file “words.txt” contains 87314 English words, including the word that completes the puzzle. This file is available online with the source code for the book. Write a

Write a program that receives a filename as user input. The file is structured as multiple lines containing numbers separated by a single space.For example, this would be an acceptable file:
1 2 3 4 5 6 7 2
Your program should open this file and:
print all its contents;
write the median of all numbers to a new file called result.txt.
IMPORTANT NOTES:
the median is the element in the middle when you sort the values;
the median of values (2, 1, 3) is 2, because when you sort them, you get 1, 2, 3, and 2 is the value in the middle.
you can assume there will be no empty lines;
there might be any arbitrary number lines in the file;
there might be any arbitrary number of elements in a single line;
you can assume there will always be an odd number of elements.
Example 1:
If input is:
file1.txt
and the contents of file1.txt are:
1 2 2
you should first print the content, and then write 2 to result.txt.
Example 2:
If input is:
file2.txt
and the contents of file2.txt are:
1 2 3 4 5 1 7

- You have been hired at an open-air mine. You are to write a program to control a digger. For your task, you have been given a `map' of all the underground resources in the mine. This map comes as a file. The file has n rows. Each row has n space-separated integers. Each integer is between zero and one hundred (inclusive). The file should be understood to represent a grid, n wide by n deep. Each square in the grid can contain valuable resources. The value of these resources can go from zero (no resources) to 100 (max resources). The grid maps the resources just below the surface, and down to the lowest diggable depths. The digger starts at the surface (so, just on top of the topmost row in the grid)—at any horizontal position between 1 and n. The digger cannot dig directly downwards, but it can dig diagonally in either direction, left-down, or right-down. In its first time-step, it will dig onto the first row of the grid. In its second time-step, it'll hit the second row, and so on.…arrow_forwardUpload only 1.c file. Any filename. Create a program that accepts a number num and returns each place value in the number.

The file should be read using the file.readlines() method. The input file contains a list of alphabetical, ten-letter strings, each on a separate line. Your program should output all strings from the list that are within that range (inclusive of the bounds).
