Time to combine everything Please write the function largestDigit(), that adheres to the following requirements: 1. There is one parameter 2. There is one retum value 3. The function must check that the parameter is a integer. If it is not an integer, return -1. 4. The function will check a number, and return the largest digit that is in the number 5. You may assume that the parameter is scalar Hints . Dividing by 10 would effectively shift every number to the right by 1 in terms of number place The rem() or mod() functions may be useful in determining the the digit in the ones place. Simply calculate the remainder when divided by 10. . WHILE LOOPS! For example, if the number is 12345, dividing by 10 and then doing something to it to remove the decimal values would return 1234, which is everything except the last digit. Likewise, the remainder when 12345 is divided by 10 is 5 function out = largestDigit(x) E% function that finds the largest digit in a given number. Returns -1 if % the input is not a whole number % Input: x - a number % Output: out - the largest digit or -1 for invalid input Examples largestDigit(12345) ---> 5 largest Digit(7394) ---> 9 largestDigit(-52) ---> 5 largestDigit(1.23) --->-1
