Whats wrong in my code both expected output and my output are same but its showing wrong answer. Can anyone help me please?
from collections import OrderedDict N=int(input()) ordered_dict=OrderedDict() for i in range(N): string=input() list1=string.split() newstr="" for i in range(len(list1)-1): newstr+=" "+list1[i] if newstr in ordered_dict: ordered_dict[newstr]=ordered_dict[newstr]+int(list1[-1]) else: ordered_dict[newstr]=int(list1[-1])
for key,value in ordered_dict.items(): print(key,str(value))

[@RIYAZALI-hy8bw]

Kuch samajh nhi aya par achha laga sun k😂😂

[@helloworld2458]

can you solve with normal dictionary or you havw to use ordereddict()? my friend told me ordereddict is dead and useless now.

[@codingcart]

Ordinary dictionary doesn't preserved the insertion order till python version 3.6 Now its updated you can solve with normal dictionary.
Try this:
od=dict()
for i in range(int(input())):
k,v=input().rsplit(' ',1)
if k in od:
od[k]=int(od[k])+int(v)
else:
od[k]=v
for k,v in od.items():
print(k,v)
