Split an array and do operation like below

Question

arr[]={1,2,3,4,5,6,2,3,5,4,3,6,7,8,9,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0}

spliter=2 // this will divide an array in to two equal parts before null element(0) found this means it will consider arr[]={1,2,3,4,5,6,2,3} and it will split an array in two equal parts arr[]={1,2,3,4,5,6,2,3,5,4,3,6,7,8,9,1}.if spliter=3 then three equal parts and likewise. spliter=1,2,3...n.and perform following operations.

skip=1 // this will skip an element skip=1,2,3...n

res[0]= 11 // 1+3+5+2

res[1]= 15 // 2+4+6+3

res[2]= 24 //5+3+7+9

res[3]= 19 //4+6+8+1 //res[index] can be vary as input spliter is vary.

This all should be dynamically.

Please help me to do this.

thanks.
