# PROBLEM:

Chef has X litres of hot water and Y litres of cold water. The current water temperature is A and he’d like it to be B. Can he achieve this?

# EXPLANATION:

Since Chef has X litres of hot water and Y litres of cold water:

- The maximum temperature Chef can attain is A+X
- The minimum temperature Chef can attain is A-Y

Notice that any temperature between these two is also easily attainable since he can only move in steps of 1.

So, Y must lie in this range: that is, the answer is “Yes” if and only if A-Y \leq B \leq A+X.

# TIME COMPLEXITY

\mathcal{O}(1) per test case.

# CODE:

## Editorialist's code (Python)

```
for _ in range(int(input())):
a, b, x, y = map(int, input().split())
print('Yes' if b >= a-y and b <= a+x else 'No')
```
