#1

sir this code is working for 3 test cases but for 4th test cases it is showing runtime error here is the code

#2

hello @tejasddongare
check the constraints->

ur solution space complexity is O(nk) that is why is showing run error for one case (nk is too much space).

try to solve this in linear space complexity.

refer this->link

#3

sir now i did space optimaztion still its failing one test case why?? rest all test cases are getting passed

#4

@tejasddongare
u r not reading sum
