Off-by-one errors are common in using the C library because it is not consistent with respect to whether one needs to subtract 1 byte – functions like fgets() and strncpy will never write past the length given them (fgets() subtracts 1 itself, and only retrieves (length − 1) bytes), whereas others, like strncat will write past the length given them.
Hash collisions can be unavoidable depending on the number of objects in a set and whether or not the bit string they are mapped to is long enough in length. When there is a set of n objects, if n is greater than | R |, which in this case R is the range of the hash value, the probability that there will be a hash collision is 1, meaning it is ...
In the above, r is the round number (0–13), and i varies from 0 to 7. The differences from the ChaCha quarter-round function are: The addition of the message words has been added. The rotation directions have been reversed. "BLAKE reuses the permutation of the ChaCha stream cipher with rotations done in the opposite directions.
In a well-dimensioned hash table, the average time complexity for each lookup is independent of the number of elements stored in the table. Many hash table designs also allow arbitrary insertions and deletions of key–value pairs, at amortized constant average cost per operation. [3] [4] [5] Hashing is an example of a space-time tradeoff.

Swap this element with the last element. Remove the last element after the swap. Down-heapify or up-heapify to restore the heap property. In a max-heap (min-heap), up-heapify is only required when the new key of element is greater (smaller) than the previous one because only the heap-property of the parent element might be violated.
