Write a function reverse which takes a string as an argument, reverses the string and returns a new string that is the reverse of the original. Note: you will need to malloc space for this new string! For example: Test char str[]="hello"; char *rts = reverse(str); printf("%s/%s", str,rts); Result hello/olleh

![Write a function reverse which takes a string as an argument, reverses the string and returns a new string that is the reverse of the original.
Note: you will need to malloc space for this new string!
For example:
Test
char str[]="hello";
char *rts reverse(str);
printf("%s/%s", str,rts);
Result
Answer: (penalty regime: 0 %)
