AnswersHow would you design a system where you have 1000 records in database and on UI you are showing them, a user can select single or bulk record which can be in any order and drag drop to reorder the sequence of the record. Example :
- Random1 June 26, 2018 in United States
I have below records
1
2
3
4
5
a user selects 1 and dragdrops it on 5th position, so the new order becomes 2,3,4,5,1. This has to be done at the database layer and in efficient way. How to maintain continuous reordering sequence of records?| Report Duplicate | Flag | PURGE

AnswerUnable to get what exactly the Question Is?
- jsd.learner April 02, 2014 in India
so What is the whole logic behind this question .It seems to be complete Math problem to me.
There is a Grasshopper in a tropical forest. The grasshopper can jump only vertically and horizontally, and the length of jump is always equal to x centimeter. A GRasshopper has found herself at the center of some cell of the chess board of the size pxq centimeters(each cell is 1x1 centimeters). She can jump as she wishes for an arbitrary number of times, she can even visit a cell more than once. the only restriction is that she cannot jump out of the board.
The grasshopper can count the number of cells that she can reach from the starting position(x,y). Let's denote this amount by dx,y. your task is to find the number of such starting position(x,y), which have the maximum possible value of dx,y
Input
The integer array contains three integers p,q,x
p= length of the board
q= width of the board
x=length of the grasshoppers jump.
Output
Output the only integer - the number of the required starting position of the Grasshopper
Example
input 2 3 1000000
output 6
input 3 3 2
output 4
