Good Operations

You are given $N$ intervals where the $i^{th}$ interval is $[L_i,R_i]$. In one operation, you will: - Choose an integer $M$ $(1 \leq M \leq N)$ and select $M$ **distinct** indices $x_1,x_2,\ldots,x_M$. - For the $i^{th}$ selected index $x_i$ (corresponding to range $[L_{x_i},R_{x_i}]$): - Choose an integer $K_i$ where $(1 \lt K_i \leq (R_{x_i}-L_{x_i}+1))$; - Pick $K_i$ **distinct** integ
