import random
n=int(input('n='))
ls=list()
for i in range(n):
  num=int(input('Input number: '))
  ls.append(num)
sz=n
print("==================   Before operation ================")
print(ls)
while sz!=0:
  ind=random.randint(0,n-1)#Pick index
  p=random.randint(-1000,1000)#choose p
  ls[ind]=p#replace
  sz-=1
print("==================   After operation ================")
print(ls)
