	// Place your snippets for c here. Each snippet is defined under a snippet name and has a prefix, body and 
	// description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:
	// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the 
	// same ids are connected.
	// Example:
	// "Print to console": {
	// 	"prefix": "log",
	// 	"body": [
	// 		"console.log('$1');",
	// 		"$2"
	// 	],
	// 	"description": "Log output to console"
	// }

有占位符的时候，可以通过tab键进行编辑

常规

"快速幂": {
  "prefix": "binpow",
  "body": [
    "int binPow(int base, int expo, int mod) {",
    "    int ans = 1;",
    "    base %= mod;",
    "    if (expo == 0) {",
    "        ans = 1 % mod;",
    "    } else {",
    "        while (expo) {",
    "            if (expo & 1) {",
    "                ans = ans * base % mod;",
    "            }",
    "            base = base * base % mod;",
    "            expo >>= 1;",
    "        }",
    "    }",
    "    return ans;",
    "};"
  ],

占位符-无默认

"占位符-无默认": {
  "prefix": "forr",
  "body": [
    "    for (int $1 = 0; $1 < $2; $1 += 1) {",
    "        ",
    "    }"
  ],
  "description": "占位符-无默认"
}

占位符-有默认

"占位符-有默认": {
  "prefix": "forr",
  "body": [
    "    for (int ${1:i} = 0; ${1:i} < ${2:n}; ${1:i} += 1) {",
