设有关键字序列{25,40,33,47,12,66,72,87,94,22,5,58},散列表长12,散列函数为h(key)=key%11,用链地址法处理冲突,请分别画出散列表,并计算ASL。
key | 25 | 40 | 33 | 47 | 12 | 66 | 72 | 87 | 94 | 22 | 5 | 58 |
H(key) | 3 | 7 | 0 | 3 | 1 | 9 | 6 | 10 | 6 | 0 | 5 | 3 |
key | 25 | 40 | 33 | 47 | 12 | 66 | 72 | 87 | 94 | 22 | 5 | 58 |
探测次数 | 2 | 1 | 1 | 1 | 1 | 2 | 1 | 1 | 2 | 3 | 1 | 3 |
ASL = (1*7 + 2 * 3 + 3 * 2) / 12 = 19 / 12
