Given $K$ arrays of length $N$ where the elements are bounded in the range $[L, R]$. The **Function value** of an array is defined as the sum of all elements present in it. In one move you can change at most $1$ element from all the arrays and the changed value must lie within the range $[L, R]$. What is the minimum number of operations required to make the function value of all arrays e
