A sorting technique is called stable if it maintains the relative order of records with equal keys (i.e., values). In other words, two equivalent elements remain in the same order in the sorted output as they were in the input.

Here's a step-by-step explanation:

1. Consider an array of elements with some of them having equal keys.
2. Apply the sorting algorithm to this array.
3. If the sorting algorithm is stable, the order of elements with equal keys will be the same in the sorted array as they were in the original unsorted array.
4. If the sorting algorithm is not stable, the order of elements with equal keys can be different in the sorted array compared to the original unsorted array.

For example, let's consider an array of pairs where each pair contains a number and a letter. The number is the key. If we sort this array using a stable sorting algorithm and two pairs have the same key, then the pair that appeared first in the original array will also appear first in the sorted array.
