In bubble sorting or selection sorting of Arrays .... If there is a Question to arrange in descending order can we just change the part of the program that displays the answer ... i mean the program will have the logic of ascending order but program gets printed in descending order by just changing the order of displaying arrays
or is it mandatory that we have to change the logic part of the program only(descending logic)???

Your task is to construct a building which will be a pile of n cubes. The cube at the bottom will have a volume of n^3, the cube above will have volume of (n-1)^3 and so on until the top which will have a volume of 1^3.

You are given the total volume m of the building. Being given m can you find the number n of cubes you will have to build?

The parameter of the function findNb (find_nb, find-nb, findNb) will be an integer m and you have to return the integer n such as n^3 + (n-1)^3 + ... + 1^3 = m if such a n exists or -1 if there is no such n.
