construct/rlve construct hack interval
construct/rlve construct hack interval: a task in MathConstructOptimize-Envs-harbor (Harbor dataset). Let f(x) be the sum of the decimal digits of x (e.g. f(1234) = 10). Construct integers L and R with 1 <= L <= R <= 5577787032466150 (that is, 10 557778703246615) such that f(L) + f(L+1) + ... +…
The task
Let f(x) be the sum of the decimal digits of x (e.g. f(1234) = 10). Construct integers L and R with 1 <= L <= R <= 5577787032466150 (that is, 10 * 557778703246615) such that f(L) + f(L+1) + ... + f(R) is divisible by 557778703246615.
