1.Write a shell script to print below pattern 0 0 1 0 1 2 0 1 2 3
#!/bin/bash
# Loop to generate the pattern
for i in {0..3}; do
for j in $(seq 0 $i); do
echo -n "$j "
done
echo "" # Move to the next line
done
3.Write a shell script to print below pattern 1 1 2 1 1 3 3 1
#!/bin/bash # Number of rows for the pattern rows=3 # Function to calculate binomial coefficient binomial_coefficient() { n=$1 k=$2 res=1 for (( i=0; i<k; i++ )); do res=$((res * (n - i) / (i + 1))) done echo $res } # Generate Pascal's Triangle for (( i=0; i<rows; i++ )); do for (( j=0; j<=i; j++ )); do # Print binomial coefficient echo -n "$(binomial_coefficient $i $j) " done echo "" # Move to the next line done
