c - why is *pp [0] equal to **pp - Stack Overflow
2016年1月27日 · That's why when you dereference pp[0] explicitly, with *pp[0], you are dereferencing it effectively twice: First you look at the contents of the address 0x2000, which is 0x1000, and then you dereference that in order to read the memory at 0x1000.
Why does Michael Sipser state that $0^p0^p$ is a bad choice ...
2023年1月13日 · First of all, you don't get to pick the decomposition. So one decomposition you'd need to handle is $x = \varepsilon$, $y = 00$, $z = 0^{2p-2}$. Now if we pump $y$ for $i$ times, we get $xy^iz = 0^{2p + 2i - 2}$, which belongs to $L$.
c++ - What does (~0L) mean? - Stack Overflow
2014年12月22日 · 0L is a long integer value with all the bits set to zero - that's generally the definition of 0. The ~ means to invert all the bits, which leaves you with a long integer with all the bits set to one.
Can the String, $0^p 0^p 0^p$, be Used with the Pumping …
The string $0^{3p}$ can always be pumped so that it stays in $L$. Recall what the pumping lemma says: there exists a $p \in \mathbb{N}$ such that any $w \in L$ of size at least $p$ can be written as $w=uvxyz$ such that $|vxy| \leq p$, $|vy| \geq 1$ …
c - What do 0LL or 0x0UL mean? - Stack Overflow
2011年8月12日 · 0x0UL is an unsigned long zero, expressed using hexadecimal notation. 0x0UL == 0UL. LL designates a literal as a long long and UL designates one as unsigned long and 0x0 is hexadecimal for 0. So 0LL and 0x0UL are an equivalent number but different datatypes; the former is a long long and the latter is an unsigned long.
0.5pp在财务或者在数学上是什么意思??是增长了0.5%,还是这次增长的百分比比上次多0…
0.5pp通常指的是百分比增长的【绝对值】,即由 1%增长至1.5%,叫增长0.5pp; 0.5%很多时候会用来做【相对增长的比值】,即由 1%增长到1.005%,叫增长0.5%
composite number Pumping Lemma for L = {$0^p$∣$p$ is a ...
2017年2月9日 · Consider the language L = {0p ∣ p is a composite number}. I know that this is not a regular language. I have thought that to prove this language is not regular take the complement (prime numbers) which must be regular, but its complement has prime numbers and 0 and 1 occurrences of 0's.
Zero power zero and $L^0$ norm - Mathematics Stack Exchange
$L^0$ norm is defined as: $$ L^p = (\sum_i|x_i|^p)^{(1/p)} $$ with $p=0$. Now this is argued to count the number nonzero elements in a vector $\textbf{x}$. If this is taken to be true, then the summation should be $1$ for any $x\neq0$ , which is true, but also $0^0$ should be $0$, which seems contradictory to arguments in calculus.
c++ - O* p = new O [5]; What does p point to? - Stack Overflow
2010年7月15日 · *p and p[0] are the same. Here are some neat features you want to know: "Pointer notation" generally refers to using the 'dereference' (or 'indirection') operator "Array notation" generally refers to using the brackets and offset value; You can represent an address in memory using either interchangeably: *p is equivalent to p[0]
