Hi @dheerajmishra992,
See the concept of bubble sort is to get the largest element to the last .Hence in this if the si==li that means that the selected index is last index so we have the largest element at last index li so we decrease li to li-1 so that the next largest number can be brought till li. So this process is taking place in the above if loop. In case arr[si]>arr[si+1] so we switch which is obvious as we want the larger element at a greater index . Further down this we have that if this is not the condition we increase si to si+1 and recursively call the function again .
