doubt in homogeneous equation
a(r) = a(r-1) + 3 it is non homogeneous linear reccurence relation right because of 3 if we remove 3 then it become homogeneous
a(r) = a(r-1) + 3 it is non homogeneous linear reccurence relation right because of 3 if we remove 3 then it become homogeneous

doubt in making cases in permutations check this
how to make cases in permutation in non increasing order, so that all cases will be covered example 4 , 1 ,1 ,1 ,1 ,1 ,1 ,1 3 ,2 , 1 ,1 ,1 ,1 ,1 ,1 2 , 2 ,2 ,1 ,1 ,1 ,1 ,1 if i have 7 , 1 , 1 ( how to make cases for this )
