Binary

  1. Binary is a base 2 number system.
  2. 0 represents False/Off and 1 represents True/On.
  3. A bit is the minimum unit of binary information stored in a computer system.

Boolean Expressions

  1. A boolean expression is a logical statement that is either TRUE or FALSE and compares data.

Truth Tables

  1. The logical operations shown in truth tables are AND, OR, XOR, and NOT.
# AND
5 > 3 and 5 == 3 + 2

True
5 < 3 and 5 == 5

False
5 == 5 or 5 != 5

True
5 < 3 or 5 != 5

False

Real Life Example using Boolean Expressions

Try changing the conditions and/or the logical operation below! Run the code to see if you are eligible to vote.

age = 16
citizen = True

if age >= 18 and citizen:
    print("You are eligible to vote.")
else:
    print("You are not eligible to vote.")

You are not eligible to vote.

UNW = 3.50
sport = True

if UNW >= 3.5 and sport:
    print("You qualify for the Sports Certificate")
else:
    print("You don't qualify for the Sports Certificate")

You qualify for the Sports Certificate

Binary Conversions

Binary to Decimal

  1. We can count in binary by using powers of 2.
  2. In binary, we read from right to left.
  3. 0111 has a value of 7.
  1. For a binary search, the list must be sorted.
  2. In a binary search, computers start at the middle (front,middle,end)
  3. The number of steps required in a binary search follows the equation: log(n)+1.
  4. Binary searches also work with a list of strings. We can sort them alphabetically.
  5. Binary searches can be represented in tree diagrams.

Binary Conversions Practice

  1. Convert the decimal number "17" into binary.
    • 10001
    • 16+0+0+0+1
  2. Convert the binary number 1010 into decimal.
    • 10
    • 8+0+2+0
  3. Convert the decimal number "122" into hexadecimal.
    • 7A
  4. Convert the hexadecimal number "09" into binary.
    • 1001

Binary Search Questions

  1. Make a binary search tree of different the list [1,2,4,15,25,30,31]
    • BinarySearchTree
  2. Put this list of strings in a order that can be used for binary search ["Donut”,"Cake”,"Soda”,"Banana”,"Fruit”]
    • ["Banana", "Cake", "Donut", "Fruit", "Soda"]
    • Must be in alphabetical order for the binary search to work
  3. Explain why Binary Search is more efficient than Sequential Search.
    • Binary search starts from the middle
    • Sequential Search starts from left to right
    • Binary search will go in the middle and is much more quicker

Extra Credit:

  • Translate the binary number, 1001010, into octal (base 8). SHOW YOUR WORK AND EXPLAIN YOUR THINKING.
    • 74 (Decimal)
    • 64+0+0+8+0+2+0
    • Octal is base 8
    • Need to put into groups of three
      • 001 001 010
    • Then each group of 3 needs to become its octal digit
      • 001 = 1
      • 001 = 1
      • 010 = 2
    • Use the three numbers and put them from left to right, and that is hte octal number
    • 112 (Octal)

OR

  • write the best rap line (determined during the lesson by group)

Binary has got 0's and 1's

use binary search a megaton

This concept is for everyone

Extra Binary Code 

decimal = int(input("Enter an integer: "))

# Uses bin to convert into decimal into binary
binary = bin(decimal)[2:]

# Output the binary
print(f"The binary equivalent of {decimal} is: {binary}")
# Output the decimal
print(f"The decimal equivalent of {binary} is: {decimal}")

The binary equivalent of 10 is: 1010
The decimal equivalent of 1010 is: 10
