15 Blue Bridge Cup 4th question

Test instructions: The Stringingrid function prints the specified string in a grid of a specified size. Requires the string to be centered in a horizontal, vertical, two direction. If the string is too long, it is truncated. If you can't just center it, you can do it slightly to the left or to a point. The following program implements this logic, please fill in the missing code in the underlined section.
Train of thought: be all kinds of output empty dizzy, but look at the solution on the original problem, a take should be some in and out.
The output expected to be int len1 = (Width-2-strlen (s))/2; int len2 = (Width-1-Len1-strlen (s)); printf ("%*s%s%*s", Len1, "", S, Len2, ""); should be int len1 = (Width-2-strlen (s))/2; int len2 = (Width-1-Len1-strlen (s)); printf ("%*s%s%*s", Len1, "", S, Len2, ""); The error is that when len1 = = 0 o'clock, the first one will output more than one space. %*s, the preceding argument is the number of bits that the string occupies, followed by the string to be output. When the length of the string is not enough, it is padded with spaces. But not when it's over. So the above error will occur.

Attach the right code:
