Statement 1: Shell sort is a stable sorting algorithm. Statement 2: Shell sort is an in-place sorting algorithm.

Statement 1: Shell sort is a stable sorting algorithm. Statement 2: Shell sort is an in-place sorting algorithm. Correct Answer Statement 2 is true but statement 1 is false

In Shell sort, the relative order of elements with equal values may change. Therefore, it is not a stable sorting algorithm. Shell sort is an in-place sorting algorithm as it requires O(1) auxiliary space.
