My code: https://www.codechef.com/viewsolution/33304957

Please can someone point out my mistake? My approach is first I check for contiguous subarray using bool type visited array & then check for distinct frequency using map. Its showing correct output for given test cases but not accepted.

Consider this case:

```
1
3
1000 500 500
```

Your are declearing the **vis** array with number of disticnt element in the input but accesing the values of the array. For this case, vis array has size 2 but you accessing vis[1000] and vis[500].

My code is giving “YES” for this. There are 3 elements that you’ve passed in the input of array.

Oops sorry bro, i got my mistake now. Such a stupid mistake I’ve done. Thankyouuu .

Updated.

Please tell me where i am wrong

```
from itertools import groupby
for i in range(int(input())):
n = int(input())
c = 0
a = list(map(int, input().split()))
g = sorted(a)
b = [len(list(group)) for key, group in groupby(a)]
h = [len(list(group)) for key, group in groupby(g)]
b = sorted(b)
h = sorted(h)
#print(b)
#print(h)
if(b == h):
#print(b)
#b = sorted(b)
d = [len(list(group)) for key, group in groupby(b)]
#for i in range(len(b)-1):
# if(b[i] == b[i+1]):
# c = 0
# else:
# c = 1
for i in d:
if(i > 1):
c = 1
#print(c)
if(c == 1):
print("NO")
else:
print("YES")
else:
print("NO")
