How to compare values in two arrays and find when the index of one array exceeds the index of another

I have two arrays of equal length that I am comparing. They are both in ascending order. I would like to compare the two array and find when array1 is greater than array2, then at that point make a third array that returns a '1' at that instance. once this has happened i would like array1 to take to value of the index where that instance is and array2 to continue searching from that instance until it finds the next value that is greater and so on. for example:

Array 1: [ 1 2 4 5 8 9 11]

Array 2: [1 2 3 4 5 6 7 ]

Array 3: [0 1 1 0 1 0 0 ]

index one of array1 is not less than index one of array2 so array 3 returns 0

index one of array1 is kept

index one of array one is less than index two of array2 so array3 returns 1

index two of array1 is now taken

index two of array1 is less than index three of array2 so array3 returns 1

index three of array1 is now taken

index three of array1 is not less than index four of array2 so array3 returns a 0

index three of array1 is kept

and so on....

so array1 keeps its value until the condition is met and then it takes the value of the index at which the condition is met and array2 continues one index at a time regardless looking for a value at which the array1 index is met.

i = 1;
j = 1;
k = 1;
while k <= size(A);
    if A(i) >= B(j);
        C(k) = 0;
        k = k+1;
        j = j+1;
    else
        C(k) = 1;
        k = k+1;
        j = j+1;
        i = i+1;
    end
end

I think this does what you want. If not, I may need you to try explaining it again.

i think this is really close to what i'm looking for. here is the data on an excel sheet:

so in this data the sum1 column is being compared to the t1 total column. i start out by taking the 1.051885 from sum1 column and keep that until the t1 total column hits 1.23255 since it is larger than 1.051885. The newly recreated array would return 0's up until this point then return a 1 here. the sum1 column then uses 2.019615 since that is the row in which t1 total exceeded sum1. it then continues to the next row and since 2.090399 is larger than 2.019615 then the new array could return a 1 again. does that make sense?

Hmm, ok, how does that differ specifically from what I gave you? What did the results from my code look like, and what should they have been.

[Josh Null]

I think what you sent will work. just wanted to send the screenshot to clarify. If i have anymore troubles i'll get back on with an update. Thank you!

[Josh Null]

which variable would be sum1 and t1 total in your code?

[Josh Null]

the new array C is returning just a single value rather than an array. any ideas?

[Bob Thompson]

Is it indexing k correctly?

Unfortunately, I can't really see your screen shot at all, it's very small in the post. Without a full description of your array I would be unable to run sum1 and t1 correctly to get a similar total as you are.

[Josh Null]

I just figured it out. just played around with it until it worked. Thanks!
