Split and sum array element like below.

Question

arr[]={1,3,2,4,6,7,8,8};

split=2; // the arr[] will be divide in 2(no of splits) parts each with equal elements

skip=1; //  skip is no of element to be skipped.

size of res[] should be accordingly. 

then

res[0]=3 //1+2 

res[1]=7 //3+4

res[2]=14 //6+8

res[3]=15 //7+8 

 

split=1,2,3...n

skip=1,2,3...n

arr[]={1,2,3...n} elements

 

This should be dynamically.

Please help me to do this.

Thanks
