#1

please correct my code -> https://ide.codingblocks.com/s/472283

#2

Modified Code


at line no 6
name of map should be m not n

#3

sir, what’s the wrong with my code. please correct -> https://ide.codingblocks.com/s/472293

#4

same error as before
don’t use arr[n]
instead use arr[1000];

i have remove the error
you can check now

and plz give feedback in the previous doubt as well

#5

sir, there is still showing incorrect code.

#6

i have just remove the error

ans may be incorrect
what you are doing here??

#7

first, i reverse the map. it means, it’s key will be in descending. Now, i iterate over the array, if(a[i]!=key) the i swap. otherwise just go on the next elemen.

#8

sir, please correct my code.

#9

map<int, int>::reverse_iterator it; // reverse the ma

this statement will not reverse the map
it just provide you the iterator so that you can iterator in reverse order as well

which question you are solving?

will you want to reverse the map?

#10

No Sir, i want to solve this question using this concept.

#11

i am asking what is the question?

#13

Your logic is not correct
a[i] will never be equal to key
because in map you are iterating from back and in array you are iterating from front
so how they can be equal

correct way to doing this
