不是的。交错数组中比预期的行数少1行

def check_missing_row(arr, expected_rows):
    actual_rows = len(arr)
    if actual_rows < expected_rows - 1:
        return True
    return False

# 示例交错数组
nested_arr = [[1, 2, 3], [4, 5], [6, 7, 8], [9, 10]]
expected_rows = 5

if check_missing_row(nested_arr, expected_rows):
    print("交错数组中比预期的行数少1行")
else:
    print("交错数组中行数符合预期")
