Here is a link of water orbs that are 100% eatable and biodegradable. https://www.yahoo.com/news/scientists-created-edible-water-orbs-190204141.html

Understood. Thanks all of you. That viscosity concepts are not being applied here. I thought initially that it would have been a different liquid.

Is there any liquid based on viscosity and density that changes into ball. Obviously here, the liquid cannot be water. Other thing can be that some chemical is applied in hand( This doesn't make sense I think).

But we have to sort, so we have to convert it into numeric type. EDIT: Ok, so we can compare them as strings only. It would compare lexicographically based on ASCII values but if we store them in file again, it is stored something like this- '1' , '2+j', '3.5', '4', 'FALSE', 'TRUE' This is...

Homework Statement Read a comma separated numeric (int, float, comp, bool) values from a file and store each comma separated value in a list[/B]. Sort the list (without using in-built sort/sorted function) and write it to output file in comma separated format. In my attempt I am not able to do...

No, that is okay we can do mod n on both sides or in programming languages (% n). But that we should have get from a*b*c. Why, we have to add something with n on our own? %n or mod n should have come on its own while solving the equation.

a= nq1 + r1 b= nq2 + r2 c=nq3 + r3 a*(b*c) = a * r2r3 = r1r2r3 (a* b) * c = r1r2 * c = r1r2r3 This is showing associativity but this is wrong as if we take a =1, b=2, c=3, then, 1*2*3= 2 but r1r2r3 = 6 Edit: for n = 4 here

Hmm.. then it's wrong. Suppose if number are 1,2,3. then 1*2*3 should be 2 but from r1r2r3 answer would be 6 which is essentially 2 for modulo 4. I thought I got an answer from equations. What should I do?

Thanks, got it. Getting One side as r1r2r3 and other also as some r1r2r3. Which proves associativity.

Modulo operation I can think of but it is essentially just a operator. I have tried doing this question in many ways. Can this associativity be shown mathematically by equations? Since, by equations I am getting stuck, but I want it to solve using equations.

For writing remainder as a number I have to use Euclid's division lemma, but it then brings 1 more variable quotient into account here. Associativity of multiplication I can use but remainder hinders it.

Homework Statement Let Zn denote the set of integers {0,1,2,...n-1}. Let * be a binary operation on Zn such that a*b is the remainder of ab divided by n. Show that (Zn,*) is a semigroup for any n . Homework EquationsThe Attempt at a Solution [/B]For showing the algebraic system to be a...

Thanks, I understand the floor function aka greatest integer function. In Turbo c++ it was not giving a warning or error. I think it takes NULL->next as NULL in turbo c++

Thanks for solving queries.

Thanks it is working fine now. delAlt() is working fine for me even when there are odd number of digits. For eg: input number: 8475483 (odd number of digits) Output: 8475483 (number as separate digits in link list) 8743 ( deleting alternate nodes)
