I show here two codes i made for this one , one code satisfies case 2 and 3 and one satisfies case 1

#1

basically stuck on printing zero the right way if element is absent but please tell me my mistake in both the codes


#2

Varun, pls use the following approach in your code as :

bool function(int a[100][100],int n,int m,int val)
{
int i=0,j=m-1;
while(i<n && j>=0)
{
if(a[i][j]==val)
{
return true;
}
else
if(a[i][j]<val)
{
i++;
}
else
{
jā€“;
}

}
return false;

}
i
