Challenges faced

1. Understanding the pattern to printed
2. Analyzing the constant patterns & listing down in what condition need to print what pattern like 'A' / 'B' / 'C' / ' ' / 'o' / '-' / '|'
3. Convert understanding into Code
   • We break down the code by solving one pattern at the same time
4. Error: MISALIGNED_VAR_DECL (line: 24, col: 9): Misaligned variable declaration
   • Remove everything & rewrite the code again
