Finding sum for given number

#1


yhis was the question for the finding pairs to the given sum and have to find the all pairs.why i was getting an run time error.and is there wrong in my recursion.
in the code i was tried to exclude the item which gives the total less than sum

Hello @Chandra123,

Is this target sum pair?
Which question is this?
Can you name the problem.

Hello @Chandra123,

  1. You are not backtracking
    You are making the same recursive call twice.

  2. Where are you keeping track of the pair?

#4

Again, in your recursive code you are not keeping record of pairs.

I have modified your code:

Hope, this would help.
Give a like if you are satisfied.
