Why Try
*I've been livin' with devils and angels \ Angels, angels \ Realize you and I are in the same boat \ Same boat, yeah* Given an integer $N$, for each $1\le i \le N$, find the value of: $$ \large{\sum_{j = 1}^{N} {j - 1 \choose j - \left\lfloor \frac{j - 1}{i} \right\rfloor - 1}} $$ Since the answer can be very large, print it modulo $10^9 + 7$. Note that ${X \choose Y}$ refers to [$X$ choose $Y
