### How it works (outdated)

    ;E¡0ỤḢṬ+  Main link. Argument: A

     E¡       Do e times, where e is 1 if all elements of A are equal and 0 otherwise.
    ;  0          Append 0 to the array.
        Ụ     Grade up; yield the indices of the resulting array, sorted by their
              corresponding values in that array.
         Ḣ    Head; extract the first index, which is the index of the first occurrence
              of the minimum. For an array of equal elements, this will be the index
              of the appended 0.
          Ṭ   Untruth; for index i, yield an array of i-1 zeroes, followed by a 1.
           +  Add this array to A, incrementing the minimum.
