Explanation / Answer

int i = 1;

while (i < 10) {

    a[i] = a[i - 1];

    i++;

}

int i = 9;

while (i > 0) {

    a[i] = a[i - 1];

    i--;

}

int i = 0;

while (i < 9) {

    a[i] = a[i + 1];

    i++;

}

int i = 8;

while (i >= 0) {

    a[i] = a[i + 1];

    i--;

}

int i = 1;

while (i < 10) {

    a[i] = a[i] + a[i - 1];

    i++;

}

int i = 1;

    a[i] = 0;

    i = i + 2;

}

int i = 0;

while (i < 5) {

    i++;

}

{ 1, 2, 3, 4, 5, 1, 2, 3, 4, 5}

int i = 1;

while (i < 5) {

    a[i] = a[9 - i];

    i++;

}

{ 1, 1, 2, 3, 4, 4, 3, 2, 1, 0}
