Objective

Implement a function that cuts a string into tokens wherever any character from a caller-supplied delimiter set appears, and returns those tokens as a malloc'd, NULL-terminated array of strings.

Steps

• The function signature is char **split(char *str, char *charset);.
• Any character present in charset acts as a delimiter; consecutive delimiters produce no empty token between them.
• Allocate the array of pointers and each token string with malloc.
• Terminate the returned array with a NULL pointer.
• If str contains no tokens, return a malloc'd array whose only element is NULL.
• You may only use malloc; no other library function is allowed.
