Question

ugi square Square. 1,000,000 times and see the number Ul ll dimensional board, of type int. An element board[i][j] is a peak (either aay, or a minimum) if all its neighbors (there should be either 3, 5, or 8 ncihitlh) for any cell) are less than board[ i][j], or greater than boa program should output all elements in board, with their indices, wh peak. It should also output if a peak is a maximum or a minimum. amaximum 21. Write a program that randomly generate a 20 x 20 two-dimer j1. The

Answer 1

Answer

Executable code

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

int main() {
int array_size=20, i, j;
int array[array_size][array_size];
for(i=0; i<array_size; i++){
for(j=0; j<array_size; j++){
array[i][j]=rand()%1000 ;
//printf("%d\t",array[i][j]);
}
//printf("\n");
}
  
for(i=0; i<array_size; i++){
for(j=0; j<array_size; j++){
int min =0, max = 0;
if(i>0 && (array[i][j]>array[i-1][j]))
min =1;
else
max = 1;
if(j>0 && (array[i][j]>array[i][j-1]))
min =1;
else
max = 1;
if(i>0 && j>0 && (array[i][j]>array[i-1][j-1]))
min =1;
else
max = 1;
if(i<array_size-1 && (array[i][j]>array[i+1][j]))
min =1;
else
max = 1;
if(j<array_size-1 && (array[i][j]>array[i][j+1]))
min =1;
else
max = 1;
if(j<array_size-1 && i<array_size-1 && (array[i][j]>array[i+1][j+1]))
min =1;
else
max = 1;
if(j>0 && i<array_size && (array[i][j]>array[i+1][j-1]))
min =1;
else
max = 1;
if(j<array_size && i>0 && (array[i][j]>array[i-1][j+1]))
min =1;
else
max = 1;

if(min==0)
printf("element array[%d][%d] is peak at minimum\n", i, j);
else if(max==0)
printf("element array[%d][%d] is peak at maximum\n", i, j);
}
}

return 0;
