Cyclically rotate an array by one problem in DSA

Cyclically rotate an array by one problem (in dsa) is a DSA topic. In plain words you use it for a short Cyclically rotate an array by one problem in dsa example in a short dry-run on paper. Don’t start with a slogan — start with that picture.

Smallest example: the smallest Cyclically rotate an array by one problem in dsa example you can type. Type it, run it, and say what you see. If you can do that from memory, you know Cyclically rotate an array by one problem (in dsa).

From the example next to this theory: Cyclically rotate an array by one problem in DSA — arrays give O(1) index access; matrices are arrays of arrays.

Trap: only saying “Cyclically rotate an array by one problem in dsa” with no example. Fix that before you talk about advanced DSA.

Viva: what is Cyclically rotate an array by one problem (in dsa)? Then show the smallest Cyclically rotate an array by one problem in dsa example you can type. Then name the trap.

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

What is Cyclically rotate an array by one problem (in dsa)? Show this: the smallest Cyclically rotate an array by one problem in dsa example you can type. Trap: only saying “Cyclically rotate an array by one problem in dsa” with no example.

Example

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