cat script.ksh
echo "Enter a number here.."
read num
echo "obase=2;$num" | bc | awk '{print $0;while(match($0,/1+/)){;q=q>substr($0,RSTART,RLENGTH)?q:substr($0,RSTART,RLENGTH);$0=substr($0,RLENGTH+1)}} END{print length(q)}'
So let's say we will run it as follows.
Code:
./script.ksh
Enter a number here..
12312446577991213
101011101111100001101011011100100110001101111000101101

./script.ksh
Enter a number here..
12111113312
1011010001111000001110110001100000

EDIT: Adding a non-one liner form of solution on same now.
Code:
echo "Enter a number here.."
read num
echo "obase=2;$num" | bc | awk '{print $0;
while(match($0,/1+/)){
q=q>substr($0,RSTART,RLENGTH)?q:substr($0,RSTART,RLENGTH);
$0=substr($0,RLENGTH+1)
}
}
END {
print length(q)
}
'
