// 使用字符串match方法
const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;
void (async function () {
const arr = [];
// Write your code here
while ((line = await readline())) {
arr.push(line);
}
const getRepeatCount = (str, s) => {
return str.match(new RegExp(s, 'gi'))?.length || 0
}
console.log(getRepeatCount(...arr));
})();
