How Can I Group Dots and Filter Mismatched Bits in Data Arrays?

AI Thread Summary
Grouping dots in a coordinate system can be achieved by using sorting algorithms based on their x or y coordinates or implementing a grid system to assign dots to specific areas. For filtering mismatched bits in a string, a bitwise AND operation with a mask can convert mismatched bits to zeros, or a loop can be employed to iterate through the string and change mismatched bits to zero while retaining matched bits. These methods provide straightforward solutions without requiring advanced mathematical knowledge. The discussion emphasizes practical approaches to data organization and manipulation. Overall, these strategies can effectively address the user's challenges with data arrays.

gruoping,deleting, changing

i am a college student, i yesterday ran into these two problems, and now i have some questions.

<1> in xOy, there are lots of dots, each of which is, let's represent them by, say, (x_i,y_i), i=(0,n).
i like to group those dots together under certain constraints/conditions, so sure there will be servral groups created.
After you read my above problem, can you tell me possible solutions that come naturally to your mind (without using any high maths knowledge) ? anything, even jokes relating to ways of grouping them together are also very welcome..thankful :biggrin:

<2> I have hundreds of lines of hundreds of bits standing next to each other, ie
Code:
...1010101010010...
...0101010100111...
...0101010000000...
.......
do you have any ideas on how to rewite the whole long bit string in a way which only matched ones (1's) are allowed, any other mismatched bits will be, say, changed into zero's ?

thanx in advance.

Hi there! It sounds like you have a couple of interesting problems on your hands. Let me see if I can offer some possible solutions to your questions.

For the first problem, grouping the dots together, one possible solution could be to use a sorting algorithm to sort the dots based on their x or y coordinates. Then, you could iterate through the sorted list and group together any dots that meet your specific constraints. Another solution could be to use a grid system and assign each dot to a specific grid based on its coordinates. Then, you could group together the dots within each grid.

As for the second problem, rewriting the long bit string, one solution could be to use a bitwise AND operation with a mask that has all 1's except for the mismatched bits, which would be 0's. This would effectively change any mismatched bits to 0's. Another solution could be to use a loop to iterate through each bit and change it to a 0 if it is mismatched and leave it as a 1 if it matches.

I hope these ideas help and good luck with your problems! :)
 
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
Thread 'Variable mass system : water sprayed into a moving container'
Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
