Can anyone bring the output

Question

def main():
testCase = int(input())

while testCase>0:
LR = list(map(int,input().strip().split()))
L = LR[0]
R = LR[1]
lst=[]
flag=1
for i in range(L,R+1):
isPrime = True
for num in range(2, int(i ** 0.5) + 1):
if i % num == 0:
isPrime = False
flag = -1
break
if isPrime:
lst.append(i)

n=len(lst)
if n>1:
print(max(lst)-min(lst))
elif n==1:
print(0)
elif flag==-1:
print(-1)

testCase -=1
main()
