顺序查找算法int lin_Search(const int array[],int size,int key) { int index; for (index = 0;index <= size-1;++index) if (key==array[index]) return index; return -1; }
二分查找算法
int bin_Search(const int array[],int low,int high,int key) { int index; while ( high>= low) { index = (low+high)/2; if (key==array[index]) { return index; } else if (key > array[index]) low = index+1; else high = index-1; } return -1; }
或者
int binarySearch(int[] E,int first,int las,int K) { if (last<first) index = -1; else { int mid=(first+last)/2; if(K== E[mid]) index = mid; else if(K<E[mid]) index = binarySearch(E,first,mid-1,K); else index = binarySearch(E,first,mid-1,K); return index; } }
