1、排序测试代码：#include#include#include"d_random.h"#include"d_timer.h"usingnamespacestd;//#defineNum5000;templatevoidselectionSort(Tarr[],intn){intsmallIndex;intpass,j;Ttemp;for(pass=0;pass

2、f(arr[j]voidinsertionSort(vector&v){inti,j,n=v.size();Ttemp;for(i=1;i0&&temp

3、-1];j--;}v[j]=temp;}}//templatevoidexchangesort(vector&v){intvsize=v.size(),temp,pass,i;for(pass=0;passv[i+1]){temp=v[pass];v[pass]=v[i+1];v[i+1]=temp;}}voidbubblesort(vector&v){inttemp,n=v.

4、size(),i,j;for(i=1;iv[j+1]){temp=v[j];v[j]=v[j+1];v[j+1]=temp;}}}templateintpivotIndex(vector&v,intfirst,intlast){intmid,scanUp,scanDown;Tpivot,temp;if(first==last)returnlast;elseif(first==last-1)returnfirst;else{

5、mid=(last+first)/2;pivot=v[mid];v[mid]=v[first];v[first]=pivot;scanUp=first+1;scanDown=last-1;while(scanUp

7、-1]=v[first];v[first]=temp;}return;}else{pivotLoc=pivotIndex(v,first,last);quicksort(v,first,pivotLoc);quicksort(v,pivotLoc+1,last);}}templatevoidmerge(vector&v,intfirst,intmid,intlast){vectortempVector;intindexA,indexB,indexV;indexA=first;inde
