I need help with a script, I have a random

pawn Code:

new RandomPutPlayerInVehicle[][1] = 
{
    {1},
    {2},
    {3},
    {4},
    {5},
    {6},
    {7},
    {8},
    {9},
    {10},
    {11},
    {12},
    {13},
    {14},
    {15},
    {16},
    {17},
    {18},
    {19},
    {20},
    {21},
    {22},
    {23},
    {24},
    {25},
    {26},
    {27},
    {28},
    {29},
    {30},
    {31},
    {32},
    {33},
    {34}
}

and I need it to choose each of these ONCE! So I don't have a duplicate. Please help
