Problem:
 Score : 300 points    Problem Statement You are given two integer sequences of length N : a_1,a_2,..,a_N and b_1,b_2,..,b_N .
Determine if we can repeat the following operation zero or more times so that the sequences a and b become equal.  Operation: Choose two integers i and j (possibly the same) between 1 and N (inclusive), then perform the following two actions simultaneously :   Add 2 to a_i .  Add 1 to b_j .       Constraints  1 ≤ N ≤ 10  000  0 ≤ a_i,b_i ≤ 10^9 ( 1 ≤ i ≤ N )  All input values are integers.         Input Input is given from Standard Input in the following format:  N  a_1  a_2  ..  a_N  b_1  b_2  ..  b_N       Output If we can repeat the operation zero or more times so that the sequences a and b become equal, print Yes ; otherwise, print No .        Sample Input 1 3
1 2 3
5 2 2      Sample Output 1 Yes  For example, we can perform three operations as follows to do our job:   First operation: i=1 and j=2 . Now we have a = \{3,2,3\} , b = \{5,3,2\} .  Second operation: i=1 and j=2 . Now we have a = \{5,2,3\} , b = \{5,4,2\} .  Third operation: i=2 and j=3 . Now we have a = \{5,4,3\} , b = \{5,4,3\} .        Sample Input 2 5
3 1 4 1 5
2 7 1 8 2      Sample Output 2 No       Sample Input 3 5
2 7 1 8 2
3 1 4 1 5      Sample Output 3 No
