Above the Threshold

TIP101 Unit 1 Session 1 (Click for link to problem statements)

U-nderstand

Understand what the interviewer is asking for by using test cases and questions about the problem.

• Will the list always contain only numbers?
  • Yes.
• Can the list be empty?
  • Yes.

P-lan

Plan the solution with appropriate visualizations and pseudocode.

General Idea: Loop through a list, keep track of all elements larger than a threshold value.

1) Create a function with parameters for the "list" and "threshold"
2) Make an empty list to store "results"
3) Loop through the input list
  a) If the element is larger than the threshold, add it to the results list
4) Return the results list

I-mplement

def above_threshold(lst, threshold):
	result = []
	for num in lst:
		if num > threshold:
			result.append(num)
	return result

lst = [8,2,13,11,4,10,14]
result = above_threshold(lst, 10)
print(result)

lst = [1,2,3,4,5,6]
result = above_threshold(lst, 3)
print(result) # Output: [4, 5, 6]
