(&forall;x&forall;yP(x,y))&rarr;(&forall;x&forall;yP(y,x)) Here the LHS will be true only if P(x,y) is true for every possible x and y. Since both x and y are coming from the same universe, if this is true, then their order doesn't matter for P(x, y).

plz correct me if wrong!! P(x) : perfect F(x) :friends (a)&#8765;&exist;x(P(x)) (b)&#8765;&forall;x(P(x)) (c)&forall;x(F(x)------>P(x)) (d) i am thinking in this way ALL FRIENDS ARE PERFECT - NO FRIEND IS PERFECT how to write above sentence...?? in logic

Hi, I am Suraj Kesharwani, I have scored AIR: 372 in GATE 2020. My Gate-Score is 764. This was my third attempt. I had to leave my job earlier in June 2019 to prepare seriously as I decided this would be my last attempt. My previous ranks are 5793 and 7613 in GATE 2018 and 2019 respectively.

I want to thank my family, GO Community, and my friend/ Mentor Abhishek Shaw. He has cracked GATE in 2019 with AIR: 175 and has also inspired me to leave my job and prepare full time. This blog is in continuation of his preparation strategy as I have also followed it with some improvements....

I must have added I assumed negative edge triggered flip flop. Now for A case, the output of first flip flop given to the next one is same as f due to double inversion. But is it of same phase? Also if a waveform is passed through a D flip flop using a clock which is in sync with the waveform, phase change happens?

@akash @arjun sir .. apology for wrong info. Is it the work of compiler ? I'm not sure.

P = Average Rotational Latency = 12.5 ms Q will depend upon how many bytes to be transferred. But how much is that?

p*p = q p*p*p = p*q //left operations with p (p*p)*p = p*q //associative property q*p = p*q //p*p=q m not getting 2nd part.

For answering there is no need to execute the query, we can directly answer this as $2$ How? Group by Student_Names It means all name that are same should be kept in one row. There are $3$ names. But in that there is a duplicate with Raj being repeated $\implies$ Raj produces ...
Let $G = (V, E)$ be a simple undirected graph, and $s$ be a particular vertex in it called the source. For $x \in V$, let $d(x)$ denote the shortest distance in $G$ from $s$ to $x$. A breadth first search (BFS) is performed starting at $s$. Let $T$ ... of $G$ that is not in $T$, then which one of the following CANNOT be the value of $d(u) - d(v)$? $-1$ $0$ $1$ $2$
