Hint: if you use 16bit -
1) 0x10 + 0xfe = 0x10e
2) 0x20 + 0xfe = 0x11e
And in 8 bit:
1) 0x10 + 0xfe = 0x0e
2) 0x20 + 0xfe = 0x1e
So it is more about overflow than reset.
Hello I am reading "The Theory of Numbers, by Robert D. Carmichael" and stuck in an exercise problem,
Find numbers x such that the sum of the divisors of x is a perfect square.
I know sum of divisors of a x = p_1^{{\alpha}_1}.p_2^{{\alpha}_1}...p_n^{{\alpha}_1} is
Sum of divisors...
B is playing a game in which he has to choose a number A between 0 and 1/2 and his probability of winning if he choose A is A^2.
I have encountered this at middle of some-other problem and couldn't make a move...
Prove that least two humans named John should have born on same day(means with same D.O.B) if world has only 24 million humans and their alphabet chart contain just 4 letter 'J','H','O' and 'N' and there can't be more than one million humans of same name and world started just 2739 years ago...
I am studying Introduction to linear Algebra by Gilbert Strang while calculating the particular solution P for $Ax=b$,he made the free variables $0$ to calculate the particular solution and said that P along with linear combinations of null space solutions make up the complete set.
I understood...
In,
\frac{1}{a}+\frac{1}{b}+\frac{1}{c}=1+\frac{1}{abc}
L.H.S to be greater than one (a,b) should be (2,3) substituting them rest is linear equation
\frac{1}{2}+\frac{1}{3}+\frac{1}{c}=1+\frac{1}{6c}
c=5
Since modulo is "zero" there is no remainder.
\frac{(ab-1)(bc-1)(ca-1)}{abc} is not a fraction
abc-a-b-c+\frac{1}{a}+\frac{1}{b}+\frac{1}{c}-\frac{1}{abc} is not a fraction
So the little terms must sum it up to zero or 1 so,
\frac{1}{a}+\frac{1}{b}+\frac{1}{c}-\frac{1}{abc}=0(let)...
Thanks for the link,I have gone through it.
But as far as I understood partition function doesn't give the number of partitions of specific cardinality.I mean if we want only the partitions that contains r terms for example or can we define a restricted partition function that can do the job?If...
Find the number of different combinations of r natural.numbers that add upto n
I tried this for quite a fair amount.of.time but.couldn't figure it out.(Punch)
Re: find f and t
It may not be an ellegent one i just gave it a shot$$
\begin{align*}c^2+2c+1&=4a^4\\c&=2a^4-b^2\end{align*}$$
I gave a try at a=2 so b is 5 and c is 7.
And 7 is also the first prime to satisfy both equations even individually too.
So r is -52 and t is -210
