• Usage:

  multiSubsets(L,n)

  multiSubsets(m,n)

• Inputs:
  • L, a list,
  • n, an integer,
  • m, an integer,
• Outputs:
  • a list,

i1 : L={a,b,c}

o1 = {a, b, c}

o1 : List

i2 : multiSubsets(L,2)

o2 = {{a, a}, {a, b}, {b, b}, {a, c}, {b, c}, {c, c}}

o2 : List

i3 : multiSubsets(3,2)

o3 = {{0, 0}, {0, 1}, {1, 1}, {0, 2}, {1, 2}, {2, 2}}
