Implement the following function in C programming language that get a string, and compute an array of non-empty tokens of the string containing only lower-case letters. For example: ● For a string "abc EFaG hi", the list of tokens with only lower-case letters is ["abc", "hi"]. ● For a string "ab 12 ef hi ", the list of such tokens is ["ab","ef","hi"]. ● For a string "abc 12EFG hi ", the list of such tokens is ["ab","hi"]. ● For a string " abc ", the list of such tokens is ["abc"]. ● For a string "+*abc!! B" the list of such tokens is empty. That is, we break the string using the spaces as delimiters (ascii value 32), and look only at the tokens with lower-case letters only . The function get_tokens gets a string str, and returns the array with the tokens containing only lower-case letters in the correct order. The length of the array should be the number of tokens, computed in count_tokens. char** get_tokens(const char* str); For example: ● get_tokens("abcEFaG hi")needstoreturn["abc","hi"] ● get_tokens("++a+b+c")needstoreturn["b","c"]. ● get_tokens("ab12ef+")needstoreturneitherNULLoranemptyarray. Remark: Note that the returned array and the strings in it must all be dynamically allocated.

-
● For a string "ab 12 ef hi ", the list of such tokens is ["ab","ef","hi"].
-
● For a string "abc 12EFG hi ", the list of such tokens is ["ab","hi"].
-
● For a string " abc ", the list of such tokens is ["abc"].
-
● For a string "+*abc!! B" the list of such tokens is empty.
That is, we break the string using the spaces as delimiters (ascii value 32), and look only at the tokens with lower-case letters only . -
