search.ts

function search(text:string, pattern:string): number {
    let i:number = 0
    let j:number = 0

    for (i = 0; i < text.length; i++) {
        for (j = 0; j < pattern.length && i + j < text.length; j++) {
            if (text.charAt(i + j) != pattern.charAt(j)) {
                break
            }
        }

        if (j == pattern.length) {
            return i
        }
    }

    return -1
}

console.log(search("ababacaba", "abac"))
