Please help me fix the error and give sorted output.(my program is implement a hash table of 29 buckets to store string data in sorted)
in the following format:
hashTable[index] -> (this node data, this nodes count, next nodes data) -> (this node data, this nodes count, next nodes data) -> . . . . . -> NULL
For example: index is 29
hashTable [29] -> ( dummy, 0, Adam) -> (Adam, 1, Ben) -> (Ben, 2, Brian) -> (Brian, 2, Chuck)........................ -> NULL
string in test file
