단순 구현문제

t = int(input())
for tc in range(1,t+1):
    n = int(input())
    arr = [[0]*n for _ in range(n)]

    for i in range(n):
        if i ==0:

            continue
        for j in range(0,n):
            if 1<=j<n-1:
                arr[i][j] = arr[i-1][j-1] + arr[i-1][j]
            elif j ==0:
