What will the following array look like after exactly four passes of the bubble sort (assume bubbling up small elements from right to left as discussed in class) that is intended to sort the array in ascending order? The left is the beginning of the array.

87, 43, 56, -10, 77, 39, 88, 23, 45, -2

(Write your solution as comma separated numbers with no spaces in between.)
