A mаx-heаp with cаpacity 10 and size 9 is stоred in an array with the fоllоwing content: A(1)=-1, A(2)=-9, A(3)=-3, A(4)=-13, A(5)=-11, A(6)=-7, A(7)=-5, A(8)=-17, A(9)=-15. Note that we have used parentheses rather than square brackets to denote the element of the array due to the syntax of Canvas. The following questions are all about applying a specific operation to the max-heap described in the above (not the resulting max-heap). (a1) After ExtractMax(A) to the max-heap at the start of this question, what is the value of A(1)? [a1] (a2) After ExtractMax(A) to the max-heap at the start of this question, what is the value of A(3)? [a2] (a3) After ExtractMax(A) to the max-heap at the start of this question, what is the value of A(7)? [a3] (a4) After ExtractMax(A) to the max-heap at the start of this question, what is the value of A(9)? [a4] (b1) After Insert(A, 0) to the max-heap at the start of this question, what is the value of A(2)? [b1] (b2) After Insert(A, 0) to the max-heap at the start of this question, what is the value of A(5)? [b2] (b3) After Insert(A, 0) to the max-heap at the start of this question, what is the value of A(10)? [b3] (c1) After Increasekey(A, 9, -2) to the max-heap at the start of this question, what is the value of A(2)? [c1] (c2) After Increasekey(A, 9, -2) to the max-heap at the start of this question, what is the value of A(4)? [c2] (c3) After Increasekey(A, 9, -2) to the max-heap at the start of this question, what is the value of A(9)? [c3]
