WebFor the first graph I used only TikZ. There are some tricks. Multiple parts in a node are not so easy to use : I use inner xsep=2ex because I don't find another way. WebFor example, the hash value of 1 is 01, so its initial bucket is bucket 01. The hash value of 2 is 10, so its initial bucket is bucket 10. And so on for each entry. Extendible hashing index: Initially, the index has four buckets, labeled 00, 01, 10, and 11. We insert the entries into their initial buckets based on their hash values, as follows:

Web(40 points) 1) Suppose that we have an extendible hashing index with the following state: Assume that every index bucket (block) can store up to 4 values. Consider now the following values: (449,124, 654, 831,1016,176, 285, 468, 615, 340, 331,135, 667,177) Insert these values into the index above using the insertion algorithm of extendible hashing. WebEngineering Computer Science Hashing is a technique to convert a range of key values into a range of indexes of an array. Load Factor is a measure of how full the hash table is allowed to get before its capacity is automatically increased which may cause a collision. When collision occurs, there are two simple solutions: Chaining and Linear Probe.
