Solution:

FInd xmin, ymin and xmax ymax,

The rectangular's left-bottom corner is (xmin-1, ymin-1)

The rectangular's right-top corner is (xmax+1, ymax+1)

N = int(input())

xmin = 102
ymin = 102
xmax = 0
ymax = 0

for i in range(N):
    s = input().split(",")
    cx = int(s[0])
    cy = int(s[1])
    if cx < xmin:
        xmin = cx
    if cx > xmax:
        xmax = cx
    if cy < ymin:
        ymin = cy
    if cy > ymax:
        ymax = cy

print(str(xmin-1)+','+str(ymin-1))
print(str(xmax+1)+','+str(ymax+1))
