Indexed Sequential Access Method (ISAM) is a combination of contiguous andlinked list implementation. Initially, the key is hashed to produce an index intoan array For example, the array may have 26 entries, each representing the lettersof the alphabet. The hash function will take the first letter of the key and findit's position 1-26 in the array. In the array is a pointer to a linked list of nodeseach of which starts with the corresponding letter. Write algorithms to insert anentry into the list and to find an entry in the list.
