C$++$

Write a program that reads a list of integers from input into a vector and outputs "yes" if the list is sorted in ascending order between two provided positions. Otherwise, output $"$no$".$ The first input specifies the number of items in the list. The next set of inputs is the lidt. The last two inputs are the start and end positions $($inclusive$).$ Assume the list contains less than $20$ integers and position $1$ is the first element.

Ex: if the input is :

$8$

$56743210$

$13$

The output is: yes

Ex if the input is:

$6$

$123452$

$46$

Then the output is:

No
