WebSep 16, 2014 · This function is basically a one-way copy. First (1), you save the address, not the value, of pop in the temp pointer. So *temp is the same as pop. Second (2) you overwrite pop with the contents of buffer. Now pop is equal to buffer. Third (3) you overwrite buffer with the contents of whatever temp points to. WebSort the array in decreasing order using the value/weight ratio. Start taking the element having the maximum value/weight ratio. If the weight of the current item is less than the current knapsack capacity, add the whole item, or else add the portion of the item to the knapsack. Stop adding the elements when the capacity of the knapsack becomes 0.
