The sum of all elements between k1'th and k2'th smallest elements

The sum of all elements between k1'th and k2'th smallest elements is simple if you keep it on paper. Isha uses it for The sum of all elements between k1'th and k2'th smallest elements on Isha's board in a first job task.

The sum of all elements between k1'th and k2'th smallest elements on the board: one The sum of all elements between k1'th and k2'th smallest elements step Isha can write from memory. Then say what The sum of all elements between k1'th and k2'th smallest elements on Isha's board looks like after.

The sum of all elements between k1'th and k2'th smallest elements exists so Isha can keep The sum of all elements between k1'th and k2'th smallest elements on Isha's board correct in a first job task.

Isha ships The sum of all elements between k1'th and k2'th smallest elements in a first job task. That is the use case worth saying.

The sum of all elements between k1'th and k2'th smallest elements trap: skipping the failure case for The sum of all elements between k1'th and k2'th smallest elements. Isha loses marks for that every viva.

After The sum of all elements between k1'th and k2'th smallest elements, Isha should still remember skipping the failure case for The sum of all elements between k1'th and k2'th smallest elements.

Close The sum of all elements between k1'th and k2'th smallest elements with: “If I skip it, The sum of all elements between k1'th and k2'th smallest elements on Isha's board goes wrong like this: skipping the failure case for The sum of all elements between k1'th and k2'th smallest elements.”

Exam tip

Board: The sum of all elements between k1'th and k2'th smallest elements on Isha's board. Dry-run The sum of all elements between k1'th and k2'th smallest elements. Name the trap: skipping the failure case for The sum of all elements between k1'th and k2'th smallest elements.

Example

# The sum of all elements between k1'th and k2'th smallest elements
data = [4, 1, 3]
print("start", data)
if data[0] > data[1]:
    data[0], data[1] = data[1], data[0]
print("after one step", data)

The sum of all elements between k1'th and k2'th smallest elements: dry-run [4, 1, 3]. Say the list after one step.

Short notes

  • DefThe sum of all elements between k1'th and k2'th smallest elements — Isha uses it for The sum of all elements between k1'th and k2'th smallest elements on Isha's board in a first job task.
  • RuleThe sum of all elements between k1'th and k2'th smallest elements → one The sum of all elements between k1'th and k2'th smallest elements step Isha can write from memory.
  • RememberThe sum of all elements between k1'th and k2'th smallest elements + a dry-run table (a first job task).
  • UseThe sum of all elements between k1'th and k2'th smallest elements in a first job task (The sum of all elements between k1'th and k2'th smallest elements on Isha's board).
  • TrapThe sum of all elements between k1'th and k2'th smallest elements — skipping the failure case for The sum of all elements between k1'th and k2'th smallest elements.
  • ExThe sum of all elements between k1'th and k2'th smallest elements → The sum of all elements between k1'th and k2'th smallest elements on Isha's board.
