To print Pascal's Triangle Pattern in TypeScript, you can use nested loops where the outer loop controls the rows and the inner loop calculates the values for each row based on the binomial coefficient formula.
In this example,
n
to represent the number of rows in Pascal's triangle.pascal
to store the triangle values.function printPascalsTriangle(n: number): void {
let pascal: number[][] = [];
for (let i = 0; i < n; i++) {
pascal[i] = [];
for (let j = 0; j <= i; j++) {
if (j === 0 || j === i) {
pascal[i][j] = 1;
} else {
pascal[i][j] = pascal[i - 1][j - 1] + pascal[i - 1][j];
}
process.stdout.write(pascal[i][j] + ' ');
}
console.log();
}
}
let rows: number = 5;
printPascalsTriangle(rows);
