The question is to find the common elements in two arrays .The code which i wrote have the complexity of order n square.
How it can be done in linear timeCode:void main () { int i,j; int a[]={1,2,3,4}; int b[]={4,5,7,1}; for (i=0;i<4;i++) { for (j=0;j<4;j++) { if (a[i]==b[j]) { printf("%d",a[i]); } } } }
