I was looking for something over the web when I came across this question. Have no idea of how to solve it. Help me out please.

Suppose we have an array a1,a2,... ,an, b1,b2,..., bn

How to change this array to a1,b1,a2,b2, ..., an,bn in O(n) time and in O(1) space.

I'm going through a Fortran code, and one bit has me a little puzzled. There is a subroutine, say SUBROUTINE SSUB(X,...) REAL*8 X(0:N1,1:N2,0:N3-1),... ... RETURN END Which is called in another subroutine by: CALL SSUB(W(0,1,0,1),...) where W is a 'working array'. It appears that a specific… >>> More
