Develop an algorithm, in the form of a Raptor flowchart, to generate odd numbers

from $1$ to a positive integer $N$ provided as input. The algorithm is described by the

pseudocode given below.

Start

Read in $N$

Set $x$ to $1$

While $(x$ less than or equal to $N)$ do $6$ and $7$

Write $x$

Set $x$ to $x+2$

End

The following are four examples of the expected input$/$output behavior of the

algorithm:

$N=4$ output: $13$

$N=5$ output: $135$

$N=6$ output: $135$

$N=7$ output: $1357$
