Difference Between Array and Slice in Go | Dataford Interview Questions

What is the difference between an array and a slice in Go?

Asked in the Golang deep-dive interview stage. Implement a simulator that exposes the difference through mutation and append behavior.

Contract

model_go_array_slice(initial, operations) receives an integer list and operations. The initial slice has length and capacity equal to len(initial), and initially shares storage with the array. Return one snapshot for every snapshot operation, each containing the current array and slice lists.

Operations are dictionaries: {"op": "set_array"|"set_slice", "index": i, "value": v}, {"op": "append", "value": v}, or {"op": "snapshot"}.

Constraints

1 <= len(initial) <= 1000
1 <= len(operations) <= 2000
All set_array indices are valid for the initial array
All set_slice indices are valid for the current slice
Operation values are integers
At least one snapshot operation is present
