Concept explainers

Concept of flowchart

A flow chart diagram is a collection of symbols that represents the steps involved in a process. It is a generic tool that can be adapted for various purposes. It is one of the most common process analysis tools. It is used for the graphical analysis of an algorithm. It helps to represent the flow of the process from the input to output. A flowchart that represents the workflow of activities is known as an activity diagram.There are so many ways that can help people to understand computer technologies and their applications. One of them is a flowchart diagram.

Question

Need to make a flowchart diagram

The image contains Python code that deals with comparing two lists of letters and categorizing their combinations. Here's how the code is structured:

```python
list1 = ['A', 'B', 'C', 'E', 'J']
list2 = ['A', 'A', 'C', 'D', 'B', 'E', 'Z', 'B', 'A', 'F', 'B', 'H', 'A']
letter_combinations = []
repeated_combinations = []

def combination():
for i in list1:
for j in list2:
if (i, j) in letter_combinations:
repeated_combinations.append((i, j))
else:
letter_combinations.append((i, j))
return letter_combinations

def repeats():
for i in list1:
for j in list2:
if ((i, j) in letter_combinations and (i, j) not in repeated_combinations):
repeated_combinations.append((i, j))
elif (i, j) not in letter_combinations:
letter_combinations.append((i, j))
return repeated_combinations

print("letter_combinations:")
print(combination())
print("repeated_combinations:")
print(repeats())
```

### Explanation:

- **Variables:**
- `list1` and `list2` are predefined lists containing letters.
- `letter_combinations` is a list meant to store unique combinations of letters from `list1` and `list2`.
- `repeated_combinations` is a list to store combinations that appear more than once.

- **Functions:**
- `combination()`:
- Iterates over every pairing of elements from `list1` and `list2`.
- If the pair `(i, j)` is already in `letter_combinations`, it's added to `repeated_combinations`. Otherwise, it's added to `letter_combinations`.
- Returns `letter_combinations`.

- `repeats()`:
- Similar loop over elements from `list1` and `list2`.
- Checks if the pair `(i, j)` exists in `letter_combinations` but not in `repeated_combinations`, then adds it to `repeated_combinations`.
- If not in `letter_combinations`, adds it.
- Returns `repeated_combinations`.

- **Output:**
-

Read two lists, list1 and list2, containing letters.

Declare lists: `letter_combinations` and `repeated_combinations` to hold data elements.

Loop `i = 0` to the length of `list1`
    Loop `j = 0` to the length of `list2`
        If `(list1[i], list2[j])` exists in `letter_combinations` then,
            Append `(list1[i], list2[j])` to `repeated_combinations`
        Otherwise,
            Append `(list1[i], list2[j])` to `letter_combinations`
        End if
    End j
End i

Print the lists `letter_combinations` and `repeated_combinations` using a proper method.

End
