1582. Special Positions in a Binary Matrix
Given an m x n binary matrix mat, return the number of special positions in mat.
A position (i, j) is called special if mat[i][j] == 1 and all other elements in row i and column j are 0 (rows and columns are 0-indexed).
/**
* @param {number[][]} mat
* @return {number}
*/
var numSpecial = function(mat) {
const m = mat.length;
const n = mat[0].length;
// Count how many 1s appear in each row
const rowCount = new Array(m).fill(0);
// Count how many 1s appear in each column
const colCount = new Array(n).fill(0);
// First pass: fill rowCount and colCount
for (let i = 0; i < m; i++) {
for (let j = 0; j < n; j++) {
if (mat[i][j] === 1) {
rowCount[🐧 Bash - Strict Mode
# Le mode strict en Bash — `set -euo pipefail`
## Principe général
Le mode strict transforme le comportement par défaut de bash : au lieu de continuer silencieusement en cas de problème, le script **échoue tôt et fort**. Cela évite les exécutions partielles silencieuses, source de bugs difficiles à diagnostiquer.
```bash
set -euo pipefail
```

## Les trois options
### `-e` — Arrêt sur erreur
Sans `-e`, si une commande échoue (code de retour non-zéro), bash continue quand même.

1. get token cat ~/.openclaw/openclaw.json | grep "token"
2. copy the token in overview -> gateway Access -> Gateway token

# Next.js App Router: Suspense と Server Components
## Suspense で Server Component を wrap する目的
Server Component が非同期処理（データフェッチ等）を含む場合、その完了までページ全体のレンダリングがブロックされる。Suspense 境界で囲むことで、該当コンポーネントの処理完了を待つ間 `fallback` を表示しつつ、ページの残りを先行してクライアントへストリーミングできる。
```tsx
import { Suspense } from 'react';
export default function Page() {
return (
<div>
<h1>Dashboard</h1> {/* 即時レンダリング */}
<Suspense fallback={<Skeleton />}>
<SlowDataComponent /> {/* データ取得完了後にレンダリング */}

Subject: Seeking New Job Opportunity – Data Scientist
Hi Hiring Team,
I am exploring new job opportunities and would like to share my background with you.
I am a Data Scientist with over 4+ years of experience in Machine Learning, Deep Learning, and Generative AI. My expertise includes classification, regression, clustering, Natural Language Processing (NLP), Transfer Learning, Large Language Models (LLMs), and MLOps. I have a proven track record of applying data-driven decision-making 1536. Minimum Swaps to Arrange a Binary Grid
Given an n x n binary grid, in one step you can choose two adjacent rows of the grid and swap them.
A grid is said to be valid if all the cells above the main diagonal are zeros.
Return the minimum number of steps needed to make the grid valid, or -1 if the grid cannot be valid.
The main diagonal of a grid is the diagonal that starts at cell (1, 1) and ends at cell (n, n).
/**
* @param {number[][]} grid
* @return {number}
*/
var minSwaps = function(grid) {
const n = grid.length;
// Step 1: For each row, compute the index of the rightmost 1.
// If a row has no 1s, store -1.
const rightmost = new Array(n).fill(0);
for (let i = 0; i < n; i++) {
let last = -1;
for (let j = 0; j < n; j++) {
if (grid[i][j] === 1) last = j;
}
rightmost[i] = last;
}
