there is a loop inside display function every time display functon is recursively called then each time the 2nd loop will intiate from i=0; then for every i=0; again function display is called how it’s going to end
please explain .

hi @dheerajmishra992
for each node you have to print all the children of that node that why we are using 2nd loop inside display function

#3

no I am just asking after which statement the value of i will reach i=1 in the second for loop

#4

@dheerajmishra992
let suppose you have a tree like this
. 1
/ \ \
2 3 4

for node 1
first it will print children of 1
then in second loop we get i=0 th child of 1 which is 2
then we print children of 2 which are none in this case.
then call will return to second for loop and the we get i=1 th child of 1 which is 3 in this case
and the process continues.

if you still have doubt you can inbox me.
