(1. Use your own value anywhere ?? appears.) 1. Find (work out) the complexity : a) $T 1=\sum_{i=1}^{n} \log i$ b) $\mathrm{T} 2=2^{2 \mathrm{-N}}$ c) Is $T 3=n \log n=0\left(n^{2} ight)$ ? 2. What will be the output : int $n 1=??, n 2=3, s=0, m=0, d=1$; int ${ }^{*} \mathrm{p} 1, { }^{*} \mathrm{p} 2 :$ pl = \&n1; $\mathrm{p] 2=\& \mathrm{n} 2$; $5=* p 1+* p 2 ;$ $\mathrm{m}=\mathrm{s}^{*}\left({ }^{*} } \mathrm{p} I ight) $; $* \mathrm{p} 2+=1$; $d=9+* p 1) /* p 2)-30 ; $ cout $
