Please solve and show all steps. This is for C++ problem.

**Title: Understanding the Runtime of Algorithms**

**Objective:**
Analyze and produce equations that asymptotically describe the runtime of the given algorithms.

**Algorithm Descriptions:**

1. **Algorithm 1:**
- **Definition:** `define algorithm_1(input)`
- **Initial Values:**
- `x = 2`
- `y = 2`
- **Computation:**
- `x = ((y + z) * 80) / 4`
- **Output:**
- `print x, y, z`

2. **Algorithm 2:**
- **Definition:** `define algorithm_2(input)`
- **Initial Values:**
- `x = 1`
- `y = 5`
- **Loop Structure:**
- `loop from x to size(input) * 4:`
- Increment `y` by 5: `y = y + 5`
- Output: `print x, y`

3. **Algorithm 3:**
- **Definition:** `define algorithm_3(input)`
- **User Input:**
- `x = user_input()`
- `y = user_input()`
- **Initial Value:**
- `z = 0`
- **Loop Structure:**
- `loop i = 0 to size(input):`
- Conditional Check:
- If `x < y`: Increment `z` by 1: `z = z + 1`
- Else: Decrement `z` by 1: `z = z - 1`

**Analysis:**

- **Algorithm 1** involves constant time operations with no loops over the input, suggesting O(1) runtime.
- **Algorithm 2** includes a loop that iterates `size(input) * 4` times, indicating a runtime of O(n), where n is `size(input)`.
- **Algorithm 3** iterates from `0 to size(input)`, and the number of operations inside stays consistent regardless of input, leading to a runtime of O(n).

**Conclusion:**
These algorithms demonstrate different patterns of efficiency, with their runtime complexities being O(1), O(n), and O(n), respectively. Understanding these will aid in predicting their performance on varying input sizes.

Follow-up Question

Use previous solution to Derive Big Oh for the algorithms from Problem 1.

This is the pervious solution starting with Step 1 and Step 2:

Step 1

- We need to provide the asymptotic equation that will describe the complexity of the provided code snippets.

Step 2 ::

1. First code ::

-> In this we have 3 operations and all the operation take constant time.

We are considering (input = n).

Lets take time taken for ::

x = 2 , y = 2 -> a (Constant time)
x = ((y + z) * 80) /4 -> b (Constant time)
print x ,y, z -> c (Constant time)

Here all are constant operations. So,

T(n) = a + b + c , which can also be written as ::

T(n) = k (Constant)

2. Second code ::

-> In this code we have a loop and so the operation will take linear time.

We are considering (input = n).

Lets take time taken for ::

x = 1 , y = 5 -> a (Constant time)
loop, (y = y + 5) , (print x, y) -> 4*n (Linear time)

T(n) = a + 4*n or,

T(n) = a + b*n ( a, b = constant)

3. Third code ::

-> In this code we have a loop and so the operation will take linear time.

We are considering (input = n).

Lets take time taken for ::

x and y input -> e (Constant time)
z = 0 -> f (constant time)
loop -> g* n (linear time)
if x < y -> h* n (linear time)
Other operations -> k (linear time)

T(n) = (e + f) + (g+h) *n + k

- We assume :: (e + f) = a , (g+h) = b

T(n) = a + bn + k ( a, b, n are constants)

Derive Big Oh for the algorithms from Problem 1.

Produce an equation that asymptotically describes the following algorithms runtime:
define algorithm_1(input):
x = 2
y = 2
x = ((y+z) * 80)/4
print x, y, z
define algorithm_2(input):
x = 1
y = 5
loop from x to size(input) * 4:
y = y +5
print x, y
Derive Big Oh for the algorithms from Problem 1.
define algorithm_3(input):
x = user_input()
y = user_input()
z = 0
loop i = 0 to size (input):
if x <y:
z=z+1
else
Z=Z-1
