**1) Suppose**

`u`and`v`both denote sets in Python. Under what condition can we guarantee that`u - (u - v) == v`?a) The sets `u` and `v` should be disjoint.

b) The set `u` should be a subset of the set `v `

c) The set `v` should be a subset of the set `u`

d) This is true for any `u` and `v`.

Answer(s) : c) The setvshould be a subset of the setu

**2) Suppose u and v both denote sets in Python. Under what condition can we guarantee that u|v == u^v?**

a) The sets `u` and `v` should be disjoint.

b) The set `v` should be a subset of the set `u`

c) The set `u` should be a subset of the set `v`

d) This is true for any `u` and `v`.

Answer(s) : a) The setsuandvshould be disjoint

**3) Suppose we insert**

`97`into the max heap`[98,67,89,38,42,54,89,17,25]`. What is the resulting heap?Answer(s) : [98,97,89,38,67,54,89,17,25,42]

**4) Suppose we we apply delete_max() twice to the heap [100,97,93,38,67,54,93,17,25,42]. What is the resulting heap?**

Answer(s) : [93,67,93,38,42,54,25,17]
