The purpose built platform
for competitive exam mastery.
Engineered for high percentiles. Verified past-year papers, adaptive mocks, and AI-powered diagnostic analytics for GATE, SSC, and software engineering.
Consider a hash table with 25 slots using open addressing with uniform hashing. If 20 keys are inserted into this table, what is the expected number of probes in an unsuccessful search?
Load factor α = n/m = 20 / 25 = 0.8. Under uniform hashing, the expected number of probes in an unsuccessful search is given by 1 / (1 - α) = 1 / (1 - 0.8) = 1 / 0.2 = 5.0.
