小则取从0到 middleIndex 的生成新的数组;相等则直接返回 index;然后用新生成的数组再比较,递归调用自身;但这种方法,每次递归需要记录递归开始的位置,然后最后查找到的时候,才能用查找到的...index加或减开始的位置。...官方算法: 从 数组中间 开始查找,声明 left、right 代表要查找的数组起始位置和结束位置 使用...
middle = low + (key - array[low])*(high - low) / (array[high] - array[low]); if(key < array[middle]){ return interpolationSearch(array, key, low, middle - 1); }else if(key > array[middle]){ return interpolationSearch(array, key, middle + 1, high); } else{ return middle;...
