#include <bits/stdc++.h>

using i64 = long long;

void solve() {
    int n;
    i64 k;
    std::cin >> n >> k;

    std::string s;
    std::cin >> s;

    for (int l = 0, r; k && l < n; l = r) {
        for (; l < n && s[l] == '1'; ++l);
        for (r = l; r < n && s[r] == '0'; ++r);
        std::fill(s.begin() + l, s.begin() + r, '1');
        --k;
    }

    std::cout << s << '\n';
}

int main() {
    std::cin.tie(nullptr)->sync_with_stdio(false);

    int t;
    std::cin >> t;

    while (t--) {
        solve();
