Sort the array of strings according to alphabetical order defined by another string

Sort the array of strings according to alphabetical order defined by another string sits in the roll list. Riya’s job is names A→Z. Write that first.

Do Sort the array of strings according to alphabetical order defined by another string once by hand. n log n vs n². Change one input. Say the new result out loud.

Without Sort the array of strings according to alphabetical order defined by another string, the roll list gets messy and names A→Z is hard to trust.

Use Sort the array of strings according to alphabetical order defined by another string when names A→Z must stay clear. If a simpler DSA step works, use that instead.

Sort the array of strings according to alphabetical order defined by another string trap: unstable sort when equal keys matter. Riya loses marks for that every viva.

After Sort the array of strings according to alphabetical order defined by another string, Riya should still remember unstable sort when equal keys matter.

One breath for Sort the array of strings according to alphabetical order defined by another string, then names A→Z, then unstable sort when equal keys matter. Sit down.

Diagram

  index →  0    1    2
  array → [10,  20,  30]

Exam tip

Say Sort the array of strings according to alphabetical order defined by another string in one breath, then n log n vs n², then unstable sort when equal keys matter.

Example

arr = [10, 20, 30, 40]
print(arr[2], arr[-1])
matrix = [[1, 2], [3, 4]]
print(matrix[1][0])  # 3

Sort the array of strings according to alphabetical order defined by another string — arrays give O(1) index access; matrices are arrays of arrays.

Short notes

DefSort the array of strings according to alphabetical order defined by another string — Riya uses it for names A→Z in the roll list.
RuleSort the array of strings according to alphabetical order defined by another string → n log n vs n².
RememberSort the array of strings according to alphabetical order defined by another string + Big-O (the roll list).
UseSort the array of strings according to alphabetical order defined by another string in the roll list (names A→Z).
TrapSort the array of strings according to alphabetical order defined by another string — unstable sort when equal keys matter.
