Take some additional notes that you would like here for 3.12 and 3.13. We will be looking for additional notes from the presentation.

What are procedures?

Fill in the blanks please:

Procedure: a named group of programming instructions that may have parameters and return values.

Parameters: are input values of a procedure

Arguments: specify the values of the parameters when a procedure is called

Modularity: specify the values of the parameters when a procedure is called

Procedural Abstraction: a process that allows a procedure to be used only knowing WHAT it does, not HOW it does it

What are some other names for procedures?: method or function

Why are procedures effective?: reduces the complexity and amount of code present

Challenge 1 below: Add the command that will call the procedure.

decimal = 7

def convertToBinary(n):
    n=int(n)
    n=bin(n)
    return n[2:]
binary=convertToBinary(96)
print(binary)

1100000

Challenge 2 below: Complete the Min and Max procedure in either JavaScript and Python using the instructions from the JavaScript page. (JavaScript will get you a extra 0.1)

Array.prototype.max = function() {
    return Math.max.apply(null, this);
};
  
Array.prototype.min = function() {
    return Math.min.apply(null, this);
};

function maxMin(array, operation) {
    var res = "Error: invalid input(s)"
    if (operation == "max") {
        res = array.max()
    } else if (operation == "min") {
        res = array.min()
    }
    return res
}

var array = [1, 3, 5, 2, 4, 6]
var res = maxMin(array, "max")
console.log("Maximum of array " + array + " -> " + res)
var res = maxMin(array, "min")
console.log("Minimum of array " + array + " -> " + res)

var array = [35, 2, 65, 7, 8, 9, 12, 121, 33, 99]
var res = maxMin(array, "max")
console.log("Maximum of array " + array + " -> " + res)
var res = maxMin(array, "min")
console.log("Minimum of array " + array + " -> " + res)

i can't run javascript on my notebook but here is the expected result:

APCSP-Fastpages-1/javascript on  master [?] via ⬢ v16.17.0 via 🅒 base 
➜ node maxMin.js
Maximum of array 1,3,5,2,4,6 -> 6
Minimum of array 1,3,5,2,4,6 -> 1
Maximum of array 35,2,65,7,8,9,12,121,33,99 -> 121
Minimum of array 35,2,65,7,8,9,12,121,33,99 -> 2

Homework/Hacks: For the hw, you have two options, easy or hard. The easy hack is for a 2.7 + extra work for the full 3. The easy hack is simply creating your own procedure with your own creativity. Since there is a lot of leeway for this one, you must do additional work to get a 3. For the hard hack, below is the start to a character to binary convertor. This is just a template, but the goal is to translate "APCSP" into binary. You can delete the existing code if you want. The only contraint is that you must use a procedure. Doing this will get you a 3.

def charToBinary(x):
    output = []
    for char in x:
        decimal = ord(char)
        binary = bin(decimal)
        binary = (binary)[2:]
        output.append(f"0{binary}")
    return output

binary_output = charToBinary("APCSP")

print(binary_output)


# The output shown below is the output you are supposed to get

['01000001', '01010000', '01000011', '01010011', '01010000']
