Proposed solution

```python
def solution():
    import sys
    input = sys.stdin.readline
    for _ in range(int(input().strip())):
        n = int(input().strip())
        a = list(map(int, input().strip().split()))
        a.sort()
        s = sum(a)
        m = 0
        for i in range(n):
            m += a[i] - i
        if m % 2 == 0 and m >= 0:
            print("Yes")
        else:
