TIP102 Unit 1 Session 1 Standard (Click for link to problem statements)
Understand what the interviewer is asking for by using test cases and questions about the problem.
t
, i
, g
, e
, and r
.Q: What if the input string does not contain any of the letters t
, i
, g
, e
, or r
?
The function tiggerfy()
should take a string s and return a new string with the letters t, i, g, e, and r removed.
HAPPY CASE
Input: "suspicerous"
Expected Output: "suspcous"
EDGE CASE
Input: "Trigger"
Expected Output: "
Input: "Hunny"
Expected Output: "Hunny"
Plan the solution with appropriate visualizations and pseudocode.
General Idea: Define a function that iterates through the string and builds a new string excluding the specified characters.
1. Define the function `tiggerfy(s)`.
2. Define the characters to remove as a string `remove_chars = "tiger"`.
3. Initialize an empty string `result` to store the modified string.
4. Iterate through each character in the input string `s`.
5. For each character, check if it (in lowercase) is not in `remove_chars`.
6. If it is not, add the character to `result`.
7. Return the `result` string.
⚠️ Common Mistakes
Implement the code to solve the algorithm.
def tiggerfy(s):
# Define the characters to remove
remove_chars = "tiger"
# Initialize an empty string to store the result
result = "
# Iterate through each character in the input string
for char in s:
# If the character (in lowercase) is not in remove_chars, add it to the result
if char.lower() not in remove_chars:
result += char
# Return the new string
return result
