Let's apply the induction method, now consider 2 arrays, The minimum comes when for an element a in array X there must be the closest number in Y. Don't use B. In which situation 2 dimensional DP can be dropped to 1 dimension? Sort the array then loop over the array to find the smallest difference while storing all pairs with that difference. I need to choose m elements, from an original array of size n, where m <= n. m will be supplied in the input, along with an array of size n. The absolute difference among all pairs of elements between chosen m elements and the original array should be minimum, that is, for each element in the subarray, its absolute difference is computed from elements of the original leftover array (after . Traverse the array using a variable i over indices [0, N 3]. Then, if we come across a pair with a smaller difference, we delete all the saved pairs and start storing only pairs with the lower difference, from then on. Let's say, the sum of squares of difference (S) = a1^2 + b1^2 + a2^2 + b2^2 + + an^2 + bn^2 - 2 * (a1 * b3 + a2 * b4 + . + an * b56 + bn * a34). Use Git or checkout with SVN using the web URL.
