Just wondering why the code for below shows do in=false
#!/bin/bash
# enter your array comparison code here
# initialize arrays a b c
a=(3 5 8 10 6)
b=(6 5 4 12)
c=(14 7 5 7)
#comparison of first two arrays a and b
for x in "${a[@]}"; do
in=false
for y in "${b[@]}"; do
if [ $x = $y ];then
# assigning the matching results to new array z
z[${#z[@]}]=$x
fi
done
done
#comparison of third array c with new array z
for i in "${c[@]}"; do
in=false
for k in "${z[@]}"; do
if [ $i = $k ];then
# assigning the matching results to new array j
j[${#j[@]}]=$i
fi
done
done
# print content of array j
echo ${j[@]}
