     Refine the strategy of the selected solution to improve it. Make sure you only change {(prob*100):.1f}% of the code, which means if the code has 100 lines, you can only change {prob*100} lines, and the rest of the lines should remain unchanged. This input code has {num_lines} lines, so you can only change {max(1, int(prob*num_lines))} lines, the rest {num_lines-max(1, int(prob*num_lines))} lines should remain unchanged. This changing rate {(prob*100):.1f}% is the mandatory requirement, you cannot change more or less than this rate.
