WebNov 26, 2024 · But there is one problem. If the size of the hash table is 12289 and the maximum length of the string is 10 digits, the hash function returns 10X127 = 1270, it returns only the address between 0 and 1270, so the address between 1271 and 12288 is not used at all. The size of the hash table, 12289, is 11000000000001 in binary.
