Great content. Pls never stop posting

[@rahulrishi107]

Its a fabulous initiative. Please continue with this concept.

[@sharankarthick3364]

Informative one!

the first Python solution is not correct here: for x in v: sum += x, because X could be list, dict again

[@stylishsannigrahi]

sum_val=0
def sum_of_vals_recursive(my_dict):
global sum_val
if (type(my_dict)==dict):#processing logic for dictionary
for k,v in my_dict.items():
if(type(v)==int or type(v)==float):#if the value is a simple int/float
sum_val=sum_val + v
else:
sum_of_vals_recursive(v)#this will get invoked during 1st nested level
else:#this bit of logic is for nested ones, where it is list, set, tuple from 1st nesting
for x in my_dict:#iteration logic for set, tuple, list
if(type(x)==int or type(x)==float):#type check of elements of the value of each iterated from previous step
sum_val = sum_val + x
else:
sum_of_vals_recursive(x)#this one is for handling next set of nestng and then, it will again follow
return sum_val;
inp_dict = {'ireland':100,'india':[200,300,[400,[200,200],400]],'uk':{'scotland':[50]}}
print(sum_of_vals_recursive(inp_dict))

for SQL query why u complicated here is a simple solution :
select e.event_name , p.participant_name
from participant p
join Events e
on e.event_id = p.event_id
group by e.event_name , p.participant_name
having count(e.event_id) > 1;

It easy to answer when you are not under pressure of an interviwer. A simple problem could become enormous if you do not have a the best control of your emotions.

[@dhairyaparikh5694]

On top of that, there is a possibility that there are 2 participants with the same name but different participant ids. In that case, your solution will just return 1 name instead of 2.
That is why the interviewer stated it’s a seeming simple yet tricky question to solve.
