#day-24 April | today's question is very good, try to solve it in 15-20 mins.

pasting the solution, here for your reference:

#O(n)
class Solution:
def countCompleteSubarrays(self, nums: List[int]) -> int:
n=len(nums)
f=defaultdict(int)
x=len(set(nums))
#print(x)
r=-1
ans=0
log=False
for i in range(n):
log and print(f"i={i} and nums[i]={nums[i]}")
while(len(f.keys())!=x and r+1<n):
r+=1
f[nums[r]]+=1
log and print(f"r={r} f={f}")
if(len(f.keys())==x):
ans+=(n-r)
log and print(f"ans={ans}")
elif(r+1==n):
log and print(f"r+1==n;break")
break

f[nums[i]]-=1
if(f[nums[i]]==0):
f.pop(nums[i])
return ans

hi Team,
I am not feeing well, please expect delay in uploading video for march-23 question.
I am also, preparing contest solutions, for today's weekly contest.

BTW, what's your opinion on Q3 in today's challenge😅😂

What I see is that, now everyone is using Gen AI models during contests, since its impossible to solve all the 4 questions in 2 mins.( see leadership board)
