若以插入排序（Insertion sort）對數列（7, 10, 2, 5, 4）進行排序，下列何者是正確步驟？
A$(7,10,2,5,4) \rightarrow (7,10,2,5,4) \rightarrow (2,7,10,5,4) \rightarrow (2,5,7,10,4) \rightarrow (2,4,5,7,10)$正確答案
B$(7,10,2,5,4)\rightarrow(2,7,10,5,4)\rightarrow(2,4,7,10,5)\rightarrow(2,4,5,7,10)\rightarrow(2,4,5,7,10)$
C(7, 10, 2, 5, 4) -> (7, 10, 2, 4, 5) -> (2, 4, 5, 7, 10)
D$(7,10,2,5,4)\rightarrow(7,2,5,4,10)\rightarrow(2,4,5,7,10)$
