Problem 21 of 50

Easy

What to do

Check if a list of integers is strictly increasing — meaning each element is strictly less than the next one. Return 'Yes' if strictly increasing, 'No' otherwise. Note: equal consecutive values (like [1, 1, 2]) are NOT strictly increasing.

Key Concepts

if-statements loops lists/arrays input/output handling

Examples

Input: arr = [1, 2, 5]

Output: Yes

Input: arr = [3, 9, 5]

Output: No

Tips for Beginners

  • Focus on understanding the logic, not memorizing syntax
  • Use print statements to debug your code
  • Don't worry about input parsing - the function handles that for you
  • If stuck, try writing out your solution on paper first
