Dexter loves to solve problems. This time his friend Ashish decides to challenge him.
Ashish gives him number N, all the numbers from 1 to N can be arranged in a 2-D matrix. There can be multiple arrangements such that the value of a palpak is maximized.
What is palpak?
Suppose the matrix made by arranging the numbers is A
A new matrix is made from A (say B) whose values are calculated as:
Let the number of rows be N
Let the number of columns be M
for i from 1 to N
for j from 1 to M
B[i][j]=A[i][j]
for k from i+1 to N
B[i][j]=B[i][j]%A[k][j]
palpak is the value calculated from the matrix B as follows:
palpak=1
for i from 1 to N
sum=0
for j from 1 to M
sum=sum+B[i][j]
palpak=palpak*sum
Dexter is trying hard to solve this problem. Please help Dexter in solving this problem.
