title: Minimum number of boxes required for n objects
body: <p>There are n objects having different weights. We have to find the minimum number of boxes required to pack all weights where each box can have the maximum weight of K. Boxes can have any number of objects but weight should be less than or equal to given weight K.</p>
  
  <p>All weights are less than or equal to K.</p>
  
  <p>For example, let K= 13 and objects be {2,3,4,5,6,7,8,9} than minimum number of boxes required are 4 ,i.e, {4,9}, {5,8}, {6,7}, {2,3}</p>
  
  <p>How should I approach this problem?</p>
