Hi everyone! I was wondering if any of you want to help me with a computer science problem I have for one of my classes. I do not understand how to do it which is why I ask. Here is the problem: Write an algorithm for placing a set of pencils in order from largest to smallest (left to right).

I learned other sorting algorithms but I don't quite understand how to implement them into my own algorithm.

Thanks.

answer: when the substance contain the two parts (polar and non-polar) like soap.

explanation:

soap is produced from the basic hydrolysis of ester "saponification", it is considered as a salt of hydrocarbons. the soap molecule contains the two parts: a polar group   (-coo-na+) and a non-polar group (r-hydrocarbon part). the polar group is called the head and the tail is the non-polar group. the polar group is hydrophilic in nature (water loving) and the non-polar group is hydrophobic in nature (water repelling).the polar/non-polar nature of a substance is useful that it can dissolve the non-polar substances by the polar part and also can dissolve the polar substances by the non-polar part. it commonly used in detergents and soaps.
