Question $5($DFT$)$

$($a$)$ For below sequences, determine the specified circularly shifted versions:

i$)x[n]=\{4,3,2,1\},0n3,$ find $x[n-2{]}_{\text{m}\text{o}\text{d}4}$

ii$)x[n]=\{1,3,2,4,-1,-3\},0n5,$ find $x[-n{]}_{\text{m}\text{o}\text{d}6}$

iii$)x[n]=\{1,4,2,3,1,-2,-5,1\},0n7,$ find $x[-n+2{]}_{\text{m}\text{o}\text{d}8}$
