There are two strings, named as “str” and “substr”. The number of characters in “str”is less than 10 and the number of characters in “substr” is 3.
The number of characters does not contain the ending ‘\0’.
We will insert “substr” into “str” after the character with the max ASCII code in“str”.
We will insert at the firstmax-ASCII-code character if there are not only one.
