C语言代码稀疏矩阵转置

以下是C语言代码稀疏矩阵转置的例子：

#include <stdio.h>
#include <stdlib.h>

#define MAX_TERMS 101
#define MAX_COL 101

typedef struct {
    int row;
    int col;
    int value;
} term;

void transpose(term a[], term b[]) {
    int n, i, j, currentb;
    n = a[0].value;
    b[0].row = a[0].col;
    b[0].col = a[0].row;
    b[0].value = n;
    if (n > 0) {
        currentb = 1;
        for (i = 0; i < a[0].col; i++) {
            for (j = 1; j <= n; j++) {
                if (a[j].col == i) {
                    b[currentb].row = a[j].col;
                    b[currentb].col = a[j].row;
                    b[currentb].value = a[j].value;
                    currentb++;
                }
            }
        }
    }
}

int main() {
    term a[MAX_TERMS], b[MAX_TERMS];
    int i, j, k = 1, m, n;
    printf("Enter the number of rows and columns: ");
    scanf("%d %d", &m, &n);
    printf("Enter the elements of matrix:\n");
    for (i = 0; i < m; i++) {
        for (j = 0; j < n; j++) {
            int x;
            scanf("%d", &x);
            if (x != 0) {
                a[k].row = i;
                a[k].col = j;
                a[k].value = x;
                k++;
            }
        }
    }
    a[0].row = m;
    a[0].col = n;
    a[0].value = k - 1;
    printf("Sparse matrix:\n");
    for (i = 0; i < k; i++) {
        printf("%d %d %d\n", a[i].row, a[i].col, a[i].value);
    }
    transpose(a, b);
    printf("Transposed sparse matrix:\n");
    for (i = 0; i < k; i++) {
        printf("%d %d %d\n", b[i].row, b[i].col, b[i].value);
    }
    return 0;
}
