Problem Description
Given a text file file.txt, transpose its content. You may assume that each row has the same number of columns, and each field is separated by the ' ' character.
Example:
If file.txt has the following content:
Output the following:
Key Insights
- Each row of the file represents a separate entity, while each column represents a property of that entity.
- The output should swap rows and columns, effectively turning rows into columns and vice versa.
- The fields are separated by spaces, which makes parsing straightforward.
- The number of columns is consistent across all rows, simplifying the transposition process.
Space and Time Complexity
Time Complexity: O(m * n), where m is the number of rows and n is the number of columns in the input file. Space Complexity: O(m * n) for storing the transposed data.
Solution
To solve the problem of transposing the content of a file, we can follow these steps:
- Read the entire content of the file into memory.
- Split the content into rows, and then further split each row into its respective fields.
- Create a new data structure (like a list of lists) to store the transposed version of the data.
- Iterate through the original data structure, filling in the transposed structure by switching rows with columns.
- Finally, format the output as required and print or save it.
The main data structure used here is a list (or array) to hold the original and transposed data. The algorithmic approach involves nested loops to swap the rows and columns.
