I am not able to figure out what is the problem with my approach please help me to debug.

i am storing the unique pair in a set of string. the unique pair is represented by a string, where “;” is seperating the two numbers.

Hey @amangoel987357

if(nums[j] - nums[i] == k){
string a;
a=to_string(nums[i]);
a.push_back(’;’);
a+=to_string(nums[j]);
s.insert(a);
}

We can only push characters to string and u were trying to push nums (10^7) in it so that was the issue

to_string convert int to string
a+=b concatenates a & b if both are string
