const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;

void (async function () {
    // Write your code here
    const input = [];
    while ((line = await readline())) {
        input.push(line)
    }
    const log = (input) => {
        const source = input[0].toLowerCase();
        const target = input[1].toLowerCase();
        let count = 0;
        const arr = source.replace(/\s+/).split("");

        for (const c of arr) {
            if (c === target) {
                count += 1;
            }
        }
        console.log(count);
    };
    log(input)
})();

干，这个题目搞到最后竟然是卡在 ACM 模式的输入这里，真可笑啊
