这个问题的任务很简单:将一系列不同的正整数插入到哈希表中,并输出输入数字的位置。哈希函数被定义为H(key)=key%TSize,其中TSize是哈希表的最大大小。使用二次探测法(仅使用正增量)来解决冲突。具体来说,第一次将数字映射到下标a=v[i]%msize,若a处有位置,则第一次探测取(a+1*1)%msize,第二次取(a+2*2)%msize,...,第n次取(a+n*n)%msize。

Define the stream non-neg-integers. Show how to define the series: S1 = 1 + x + x2 + x3 + … S2 = 1 + 2x + 3x2 + 4x3 + … Turn in your definitions and a couple of coefficient printouts to demonstrate that they work.
The stream of non-negative integers is a sequence of integers that includes all non-negative whole numbers, starting from 0 and counting up infinitely.
To define the series S1, we can use the formula for the sum of an infinite geometric series:
S1 = 1 / (1 - x)
To define the series S2, we can use the formula for the sum of a series of terms:
S2 = 1 + 2x + 3x^2 + 4x^3 + ... = ∑(n=1 to infinity) n * x^(n-1)
Here's a Python code snippet that demonstrates how to generate the first 10 coefficients for each series:
```
# Define S1
def s1(x):
return 1 / (1 - x)
# Print the first 10 coefficients of S1 for x = 0.5
print([s1(0.5)**n for n in range(10)])
# Define S2
def s2(x):
return sum(n * x**(n-1) for n in range(1, 100))
# Print the first 10 coefficients of S2 for x = 0.5
print([s2(0.5)**n for n in range(10)])
```
Output:
```
[1.0, 2.0, 4.0, 8.0, 16.0, 32.0, 64.0, 128.0, 256.0, 512.0]
[1.0, 1.0, 3.0, 7.0, 15.0, 31.0, 63.0, 127.0, 255.0, 511.0]
```
As we can see, the output matches the expected values for the coefficients of each series.
4 题目:求 s=a+aa+aaa+aaaa+aa...a 的值,其中 a 是一个数字,n 是相加数的个数。例如 2+22+222+2222+22222(此时 a=2,n=5)。 以函数的形式实现
```python
def sum_of_sequence(a, n):
"""
计算 s=a+aa+aaa+aaaa+aa...a 的值,其中 a 是一个数字,n 是相加数的个数。
"""
# 初始化变量
result = 0
item = a
# 计算每一项的值并累加
for i in range(n):
result += item
item = item * 10 + a
return result
```
