#Day58 #100DaysChallenge- Matlab Loops| Finding first and last digit of the given number

#Day58-Finding first and last digit of the given number
Task:

Write a code to find first and last digit of the given number.
1234
first digit:1
last digit:4


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

Matlab code

function[first,last]=firstandlastdigit(n)

first=n;

last=mod(n,10);

while(first>=10)

    first=floor(first/10);

end

 Sample Input and Output

>> [first,last]=firstandlastdigit(456789321)

first =

     4

last =

     1

>> [first,last]=firstandlastdigit(987654326)

first =

     9

last =

     6
