Golang a generic function that finds the smallest number in an array

Golang to implement a generic function to find the minimum number of arrays, you need to use a type switch.

GOL Type switch notation:

Switch V. (type) {case Int:case float64:case string:}

The idea is to iterate over the array, to save the smaller number, and the function exits to return that number.

Golang Code:

package mainimport  (     "FMT") Func minimum (first interface{},  rest ...interface{})  interface{}{    minimum := first     for _, v := range rest {         switch v. (type)  {            case  int:                if  v := v. (int);  v < minimum. (int)  {                     minimum = v                  }                case float64:      &nbSp;         if v := v. (float64); v <  minimum. (float64)  {                     minimum = v                  }                case string:                 if v := v. (string);  v < minimum. (string)  {                     minimum = v                  }            }        }       return minimum}func main ()  {     i := minimum (1, 3, 5, 7, 9, 10, -1, 1). (int)     fmt. Printf ("i = %d\n",  i)}

Clang

#include  <stdio.h>int min_int (VOID&NBSP;*V1,&NBSP;VOID&NBSP;*V2)  {     return * (int *) v1 > * (int *) v2;} Int min_double (VOID&NBSP;*V1,&NBSP;VOID&NBSP;*V2)  {    return * (double  *) v1 > * (double *) v2;} Void *minimum (void *base, int size, int esize, int  (*min_cmp) (void  *, void *))  {    int i;    void *mini  = base;    for  (i = 1; i < size; i++)  {        if  (MIN_CMP (mini, base + i *  esize))             mini = base  + i * esize;    }       return  mini;} #define  arr_len (ARR) &Nbsp;sizeof (arr)  / sizeof (arr) [0]) #define &NBSP;ARR_ESIZE (arr)  sizeof (arr) [0]) Int main ()  {    void *min;    int arr_int[] = {0,  5, 6, 7, 8, 9, -1, 2};     min = minimum (arr_ Int, arr_len (Arr_int),  arr_esize (Arr_int),  min_int);     printf ("%d\n",  * (int *) min);     double arr_double[] = {1.1, 2.2, 3.3,  4.4, 5.5, 6.6, -3.14, 99};    min = minimum (arr_double ,  arr_len (arr_double),  arr_esize (arr_double),  min_double);     printf ("%lf\n ",  * (double *) min);     return 0;}
