Challenge #239: SEND + MORE = MONEY

A solution to last week's challenge can be found here.

For this week's challenge, we will use Designer to solve/prove a classic verbal arithmetic problem. In this case, each letter in the equation "SEND + MORE = MONEY" will have a unique value between 0 and 9. Your job is to find the solution that makes the equation true.

So I did this in kind of a crazy way...

...generating random numbers until something works. However, that did lead me to find some additional answers to this problem, albeit ones where m = 0, effectively truncating the second and third numbers in the equation.

Did it by brute force but got there in the end

Found this one really tough, had to use the solution to get me started creating the letter/number dataset.

Really enjoyed this one. I took a brute force approach here. Even then, took a while to think about the structure.

Tried a few different routes to be fancy, but ended with this approach.

Solved. That was challenging and fun!

I started by getting all the possible sets of 3 non-repeating digits.

From there, I looked at figuring out all the combos to get D + E = Y and N + R = E. What made this challenging was if there was a (I could not remember the actual word for it) carryforward value of 1 into the next column. For ex 1 + 9 = 10, the 0 would be in the reference column but the 1 would be a carryforward, so for N + R = E, I also needed to factor in N + R + 1 = E

Mod was involved. And then it was just a matter of repeating the logic and excluding invalid combos
