Program looks like......for(i=0;i<n;i++){ for(j=0;j<n;j++) {   result[i][j]=a[i][j]+b[i][j]+c[i][j]; }}loop will execute n*n times...and 2 add operations..if 1 add op takes 'c' time, thentotal time= 2*c*n*nthus, time complexity= n*n......

It depends on the amount of primary memory one has for the process. If we can store 1 million records in primary memory, then we can very well take a hash table with a consistent hashing scheme for avoiding collisions. It will take O(1). 

In most cases however this is not possible. In circumtances like this, there are two ways:

B Trees or Extensible Hashing both of them have interesting time complexities.
