Incorrect Node References in Heap Deletion Section

[desaisoham0]

Hello,

I've noticed an issue in the Heap Deletion section of the documentation. In step 3 of the "Deleting from this heap" process, the text references nodes 6 and 7, which do not appear in the provided diagram. The image correctly shows a swap between nodes 1 and 2. This seems to be a typographical error in the material.

Would it be possible to correct the step descriptions to match the illustrated nodes?

Thanks for looking into this.
