Study Notes
Division with Remainders
- The division algorithm allows determination of the quotient and remainder in division problems.
- Example 1: For 23 ÷ 5, the quotient is 4, resulting in 23 = 5×4 + 3, where the remainder is 3.
- Example 2: For 102 ÷ 7, the quotient is 14, yielding 102 = 7×14 + 4, with the remainder being 4.
Practice Problems
- Exercises include divisions such as:
- 37 ÷ 6
- 89 ÷ 8
- 54 ÷ 9
- 94 ÷ 7
- 65 ÷ 2
Real-Life Applications
- Scenario 1: Packing 52 books into boxes of 9.
- Calculation shows 5 full boxes and 1 partially filled box with 7 books.
- Scenario 2: Distributing 83 laptops among 7 schools.
- Each school receives 11 laptops with 6 remaining.
Hashing Algorithms
- A hash value is a unique fingerprint for data, generated by a hashing algorithm.
- Changes in input, like capitalization, produce entirely different hash values.
- Example: "Hello" could generate the hash 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c.
Hash Tables
- A hash table utilizes keys to store data efficiently using a hash function.
- Benefits include:
- Fast lookups allowing direct access to stored data rather than searching through lists.
- Efficient storage handling large datasets effectively without slowing down.
Application of Hashing Algorithms
- Division and remainders are used to compute keys in hashing.
- Example: In a hash table with 10 slots, a key value of 123 is stored in slot 3 (the remainder of 123 ÷ 10).
Additional Practice Problems
- Pack 128 apples into baskets of 12: find out how many baskets and leftover apples.
- Calculate the hash value for the key 37 in a hash table of size 10.
- Distribute 95 tablets across 8 classrooms and determine the leftovers.
- Distribute 123 chairs among 9 offices and establish how many are left over.
