WebApr 25, 2024 · So the largest sum divisible by 3 would be 7- (2+2)=3. Similarly, if x%3=1 and y%3=1, (x+y)%3 = 2. The approach is to iterate the array and keep track of n1 and n2. For each number k in array, if k%3 = 1, we do n2 = min (n2, n1+k) and n1=min (n1, k). If k%3 = 2, we do n1=min (n1, n2+k) and n2=min (n2, k). Webe. 16 apples and 3 oranges 29.
