Insertion at beginning

Insertion at beginning sits in lab hour. Dev’s job is a Insertion at beginning dry-run. Write that first.

Keep Insertion at beginning small. Dev should finish a Insertion at beginning dry-run in a few lines, not a 40-line dump.

Insertion at beginning exists so Dev can keep a Insertion at beginning dry-run correct in lab hour.

Use Insertion at beginning when a Insertion at beginning dry-run must stay clear. If a simpler DSA step works, use that instead.

Don’t do this with Insertion at beginning: only reciting the name of Insertion at beginning. Interviewers spot it in ten seconds.

Insertion at beginning is not a lonely heading. Dev ties it to a Insertion at beginning dry-run.

One breath for Insertion at beginning, then a Insertion at beginning dry-run, then only reciting the name of Insertion at beginning. Sit down.

Exam tip

Board: a Insertion at beginning dry-run. Dry-run Insertion at beginning. Name the trap: only reciting the name of Insertion at beginning.

Example

# Insertion at beginning
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)

Insertion at beginning: dry-run [4, 1, 3]. Say the list after one step.

Short notes
