標題[理工] [演算法] cormen兩個習題

請教一下,這是cormen的習題,有兩題不太知道怎麼寫..
1)
Rewrite the MERGE procedure so that it does not use sentinels, instead
stopping once either array L or R has had all its elements copied back
to A and then copying the remainder of the other array back into A.
2)
Insertion sort can be expressed as a recursive procedure as follows.
In order to sort A[1..n], we recursively
sort A[1..n -1] and then insert A[n] into the sorted array
A[1..n - 1]. Write a recurrence for the running time of this recursive
version of insertion sort.
希望有前輩能指導一下
謝謝幫忙

推 volleyer:第二題的recurrence...是指這個嗎 T(n)=T(n-1)+n/2 09/27 21:07
