# PROBLEM:

In a penalty shootout, team A has scored X points in 3 kicks and team B has Y points in 4 kicks.

Is it possible for scores to be tied after 5 kicks?

# EXPLANATION:

Team A can score anywhere between 0 and 2 points from their remaining tries.

So, their final points can be one of \{X, X+1, X+2\}.

Team B can score either 0 or 1 point from their remaining kick, so their final score will be either Y or Y+1.

If there’s any intersection between the sets \{X, X+1, X+2\} and \{Y, Y+1\}, the answer is `Yes`

- otherwise it’s `No`

.

# TIME COMPLEXITY:

```
for _ in range(int(input())):
x, y = map(int, input().split())
if x+2 < y or y+1 < x: print('No')
else: print('Yes')
