how does a recursive call work inside a loop?Is the iterated completely for every single recursive call or are there multiple recursive calls for a single iteration?

Yes there will be multiple recursive calls. Please refer the video on generating permutations which may be in the backtracking section of your course. There prateek bhaiya has explained the recursion. This problem is very similar to that.
I could not understand the step by step dry run of the permutation code and the influence of for loop on the results obtained by recursion call in the loop
