• [nitpick] The prompt string in the 'input_pick_array' function is slightly ambiguous regarding the '0' option versus the 'random' default. Consider rephrasing it (for example, by separating the 'Back' option from the random selection instruction) to enhance clarity.

f"Enter the number of the {desc} [1-{len(arr)}, or 0 to go back or random [default: 0]: "

python/scripts/leetcode.py:223

• [nitpick] The error message here could be more explicit. Consider rewording it to 'Failed to fetch the problem. Please verify that the problem ID {problem_id} is correct.' for improved user guidance.

print(f"Failed to fetch the problem. Check {problem_id} is correct?")
