### Question:

### Answer:

```
Please find the attached python code:
def getSquares(X,Y):
s = set()
for i in range(len(X)):
s.add((int(X[i]),int(Y[i])))
count = 0
a = list(s)
for i in range(len(X)-1):
for j in range(i+1,len(X)):
x1,y1 = a[i][0],a[i][1]
x2,y2 = a[j][0],a[j][1]
if (x1 > x2):
tmp = x1
x1 = x2
x2 = tmp
tmp = y1
y1 = y2
y2 = tmp
x3,y3 = x2+(y1-y2),y2+(x2-x1)
x4,y4 = x1+(y1-y2),y1+(x2-x1)
if ((x3,y3) in s and (x4,y4) in s):
count += 1
x3,y3 = x2-(y1-y2),y2-(x2-x1)
x4,y4 = x1-(y1-y2),y1-(x2-x1)
if ((x3,y3) in s and (x4,y4) in s):
count += 1
return (int(count/4))
X = [0,0,1,1,1,2,2]
Y = [0,1,0,1,2,1,2]
print(getSquares(X,Y))
```
