这段代码怎样改错void Headadjust(SStablel& S, int s, int m) { //分数堆排序 Elemtype rc; rc = S.R[s]; for (int j = 2 * s; j <= m; j *= 2) { if (j < m && S.R[j].score < S.R[j + 1].score)++j; if (rc.score >= S.R[j].score) break; S.R[s] = S.R[j]; s = j; } } void Creatheap(SStablel& S) { int n = S.length; for (int i = n / 2; i > 0; --i) Headadjust(S, i, n); } void Headsort(SStablel& S) { Creatheap(S); for (int i = S.length; i > 1; --i) { Elemtype x; x = S.R[1]; S.R[1] = S.R[i]; S.R[i] = x; Headadjust(S, 1, i - 1); } } void Merge(Elemtype r[], Elemtype t[], int low, int mid, int high) { //分数归并排序 int i = low; int j = mid + 1; int k = low; while (i <= mid && j <= high) { if (r[i].score <= r[j].score) t[k++] = r[i++]; else t[k++] = r[j++]; } while (i <= mid) t[k++] = r[i++]; while (j <= high)t[k++] = r[j++]; } void Msort(Elemtype r[], Elemtype t[], int low, int high) { Elemtype s[1]; if (high == low)t[low] = r[low]; else { int mid = (high + low) / 2; Msort(r, s, low, high); Msort(r, s, mid + 1, high); Merge(s, t, low, mid, high); } } void Mergesort(SStablel& S) { Msort(S.R, S.R, 1, S.length); }

在这段代码中，有两个函数名拼写错误，应该将 `SStablel` 改为 `SStable`，这可能是由于其他地方的拼写错误导致的。此外，代码中的 `Elemtype` 类型在没有给出定义的情况下使用，需要在代码开头或其他地方给出定义。

修改后的代码如下：

void Heapadjust(SStable& S, int s, int m) {         //分数堆排序
    Elemtype rc;
    rc = S.R[s];
    for (int j = 2 * s; j <= m; j *= 2) {
        if (j < m && S.R[j].score < S.R[j + 1].score)++j;
        if (rc.score >= S.R[j].score) break;
        S.R[s] = S.R[j];
        s = j;
    }
}

void Createheap(SStable& S) {
    int n = S.length;
    for (int i = n / 2; i > 0; --i)
        Heapadjust(S, i, n);
}

void Heapsort(SStable& S) {
    Createheap(S);
    for (int i = S.length; i > 1; --i) {
        Elemtype x;
        x = S.R[1];
        S.R[1] = S.R[i];
        S.R[i] = x;
        Heapadjust(S, 1, i - 1);
    }
}

void Merge(Elemtype r[], Elemtype t[], int low, int mid, int high) {   //分数归并排序
    int i = low;
    int j = mid + 1;
    int k = low;
    while (i <= mid && j <= high) {
        if (r[i].score <= r[j].score) t[k++] = r[i++];
        else t[k++] = r[j++];
    }
    while (i <= mid) t[k++] = r[i++];
    while (j <= high)t[k++] = r[j++];
}

void Msort(Elemtype r[], Elemtype t[], int low, int high) {
    Elemtype s[1];
    if (high == low)t[low] = r[low];
    else {
        int mid = (high + low) / 2;
        Msort(r, s, low, high);
        Msort(r, s, mid + 1, high);
        Merge(s, t, low, mid, high);
    }
}

void Mergesort(SStable& S) {
    Msort(S.R, S.R, 1, S.length);
}
