Finding a Hidden Benchmark Value
You are given array A with N number A= [a0, a1 .. aN-1] and array B with M numbers, B= [b0, b1 ... bM-1]. (1≤ N, M≤ 10 ^5,1 ≤ ais ≤ 10^8, 1≤ bj ≤ 10^8) SA and SB represent the respective scores of A and B, and each score is defined as the total score of the elements in each array.
When calculating SA and SB this way, calculate D which makes the biggest difference between the two. (Caution: It is Not the absolute value) If there is more than one D that maximizes the difference between SA and SB, Calculate the smallest one.
1Example 1
When D is 5, the score of A and B are 10 and 5, respectively. Then, the value of SA-SB is 5 which is also maximum.
2Example 2
When D is 0, the scores of A and B are 6 and 4 respectively. Then, the value of SA-SB is 2 which is also maximum.
3Example 3
When D is 3, the scores of A and B are 5 and 8 respectively. Then, the value of SA-SB is -3 which is also maximum. Although the maximum value of SA-SB is -3 when D is 11 or 12 as the score of A and B are 3 and 6, respectively, the answer is 3 because 3 is smaller than 11.
4Example 4
When D is 8, the scores of A and B are 2 and 4 respectively. Then, the value of SA-SB is -2 which is also maximum. Remember that the difference between SA and SB is not an absolute value.
