Follow the full solution, then compare it with the other examples linked below.

Example 3

easy
Identify the pattern: Monday → M, Tuesday → T, Wednesday → W. How would you extract the first letter of any day?

Solution

  1. 1
    Step 1: The pattern takes the first character of each string.
  2. 2
    Step 2: In code, this would be: firstLetter = dayName[0].

Answer

Extract the first character of the string. Pattern: take index 0 of each word.
Pattern recognition in programming means noticing repeating operations that can be generalised into a single rule or function.

About Pattern Recognition

Pattern recognition is the process of identifying similarities, trends, or regularities across data or problems in order to build general solutions. By spotting what is the same across different cases, you can create reusable strategies instead of solving each case from scratch.
