Implement bitmap font render/compress/invert

Bitmap Character to Image Conversion (3 phases)

You are given a bitmap lookup table (a dictionary/map) that represents a tiny “font”.

• Key : a character (e.g., 'J' )
• Value : a 2D grid (matrix) of 0/1 integers where:
  • 0 = background pixel
  • 1 = foreground pixel

Example bitmap for the letter J (10 rows × 6 columns):

0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
1 0 0 0 1 0
0 1 1 1 0 0
0 0 0 0 0 0
0 0 0 0 0 0

Phase 1: Basic printing

Implement a function that, given the lookup table and an input character, prints the character’s bitmap to the console in the same grid format (preserve rows/columns).

Phase 2: Compression & decompression

To save space, implement:

1. compress(bitmap) : Convert a 2D 0/1 matrix into a more compact representation.
2. decompress(compressed) : Restore the original 2D matrix.

Requirements:

• The decompressed bitmap must be identical to the original.
• After decompressing, print the bitmap again (reuse Phase 1 printing).

Notes:

• You may choose any reasonable compression format (e.g., row-wise run-length encoding (RLE), storing coordinates of 1 s, etc.), but it must support lossless round-trip.

Phase 3: Manipulation & reuse

Perform an additional transformation on the bitmap(s), then print the result.

• Example transformation: invert the bitmap (swap 0 and 1 ).
• You must reuse part of your Phase 2 code (e.g., decompress → manipulate → print, or manipulate compressed data then use existing logic).

Assumptions / clarifications

• All bitmaps are rectangular matrices.
• Printing can be 0/1 separated by spaces (or equivalent consistent formatting).
• The lookup table may contain multiple characters; your functions should work for any entry in the table.
