For each code snippet, state its runtime in terms of N, you can assume that the ... represents straight line code.

a) for (int i = N; i >= 0; i -= 4) { }

b) for (int i = 1; i < N; i *= 5) { }

c) for (int i = 0; i < N; i++) {

for (int j = N; j > 0; j /= 2) { }

}

d) for (int i = 0; i < N; i++) {

for (int j =N; j > i; j) { }

}

e) for (int i = 1; i < N; i=2) {

for (int j = 0; j < i; j++) { }

}
