Question
Give the equivalent pseudo code for the algorithm presented by the flow chart.

Transcribed Image Text:### Flowchart Explanation
The flowchart depicted outlines a series of tasks and decision points. Here is a detailed description of each element and the flow of the process:
1. **Start**: The process begins here.
2. **Task A**: The first task in the process. It is represented by a rectangular box.
3. **Decision - Test 1**: A decision point follows Task A, represented by a diamond shape. This decision point checks a condition referred to as “Test 1”.
4. **True Branch (Right Branch from Test 1)**:
- **Task B**: If Test 1 evaluates to true, Task B is executed. This is followed by reaching the **End** of the process.
5. **False Branch (Downward Branch from Test 1)**:
- **Decision - Test 1**: A second check for the same condition, Test 1, is made.
6. **True Branch (Right Branch from Second Test 1)**:
- **Task C**: If this secondary Test 1 evaluates to true, Task C is executed, leading directly to the **End** of the process.
7. **False Branch (Downward Branch from Second Test 1)**:
- **Task D**: If Test 1 (second check) evaluates to false, Task D is executed. After completing Task D, the flow loops back and re-evaluates the first Test 1.
8. **End**: The process concludes here.
This flowchart provides a visual representation of a logical progression of tasks based on conditional tests. It allows for efficient decision-making and ensures that specific tasks are carried out based on the results of condition checks within a system or process.
