# Coin Game 
# You are given two piles of coins where Pile A has x coins, and Pile B has y coins. In each turn, you can either pick 2 coins from Pile A and 1 coin from Pile B or 1 coin from Pile A and 2 coins from Pile B. Check whether it is possible to empty both the piles or not.



# Input Format

# The first line of input contains an integer T. In the next T lines, you are given two spaced separated integers x and y.



# Output Format

# Print "YES" if you can empty both the piles, otherwise print "NO".



# Constraints

# 1 <= T <= 105

# 0 <= x, y <= 107



# Example

# Input

# 3
