Devise an algorithim$/$code in javascript without the use of strings to receive a positive number and output "yes" if each of its digits is in a non$-$decreasing order; otherwise, output $"$no$".$ For instance, if the input is $123558,$ the program should output "yes", because if you read the digits from left to right, the values of the digits never decrease. But, if the input is $632,$ the program should output $"$no$"$ because $3$ is not larger than $6$ and $2$ is not larger than $3$
