#Day59 #100DaysChallenge- Matlab Loops| Swapping first and last digit of the given number

#Day59-Swapping first and last digit of the given number
Task:

Write a code to swap first and last digit of the given number.
1234
first digit:1
last digit:4
Swapped Number:4231



Note: This code can be done using the in-built command. But for the challenge, I am trying to avoid those.
Matlab code

function swappednum=swapfirstnlastdigits(n)

[first,last]=firstandlastdigit(n)%calling the function.

digits=floor(log10(n));

swappednum=(((last*10^digits)+(floor(mod(n,10^digits)))-last)+first);

end

 Sample Input and Output

>> swappednum=swapfirstnlastdigits(67541)

first =

     6

last =

     1

swappednum =

       17546

>> swappednum=swapfirstnlastdigits(12345)

first =

     1

last =

     5

swappednum =

       52341

>> swappednum=swapfirstnlastdigits(999834567)

first =

     9

last =

     7

swappednum =

   799834569
