Bride Hunting

Problem Description

Sam is an eligible bachelor. He decides to settle down in life and start a family. He goes bride hunting.

He wants to marry a girl who has at least one of the 8 qualities mentioned below:-

1) The girl should be rich.

2) The girl should be an Engineer/Doctor.

3) The girl should be beautiful.

4) The girl should be of height 5.3".

5) The girl should be working in an MNC.

6) The girl should be an extrovert.

7) The girl should not have spectacles.

8) The girl should be kind and honest.

He is in search of a bride who has some or all of the 8 qualities mentioned above. On bride hunting, he may find more than one contenders to be his wife.

In that case, he wants to choose a girl whose house is closest to his house. Find a bride for Sam who has maximum qualities. If in case, there are more than one contenders who are at equal distance from Sam’'s house; then

print "“Polygamy not allowed”".

In case there is no suitable girl who fits the criteria then print “"No suitable girl found"”

Given a Matrix N*M, Sam's house is at (1, 1). It is denoted by 1. In the same matrix, the location of a marriageable Girl is also denoted by 1. Hence 1 at location (1, 1) should not be considered as the location of a marriageable Girl’s location.

The qualities of that girl, as per Sam’'s criteria, have to be decoded from the number of non-zero neighbors (max 8-way) she has. Similar to the condition above, 1 at location (1, 1) should not be considered as the quality of a Girl. See Example section to get a better understanding.

Find Sam, a suitable Bride and print the row and column of the bride, and find out the number of qualities that the Bride possesses.

NOTE: - Distance is calculated in number of hops in any direction i.e. (Left, Right, Up, Down and Diagonal)

Constraints

2 <= N,M <= 10^2

Input Format

First Line contains the row (N) and column (M) of the houses.

Next N lines contain the data about girls and their qualities.

Output

It will contain the row and column of the bride, and the number of qualities that Bride possess separated by a colon (i.e. :).

Explanation

Example 1

Input:

2 9

1 0 1 1 0 1 1 1 1

0 0 0 1 0 1 0 0 1

Output:

1:7:3

Explanation:

The girl and qualities are present at (1,3),(1,4),(1,6),(1,7),(1,8),(1,9),(2,4),(2,6),(2,9).

The girl present at (1,3) has 2 qualities (i.e. (1,4)and (2,4)).

The girl present at (1,4) has 2 qualities.

The Bride present at (1,6) has 2 qualities.

The Bride present at (1,7) has 3 qualities.

The Bride present at (1,8) has 3 qualities.

The Bride present at (1,9) has 2 qualities.

The Bride present at (2,4) has 2 qualities.

The Bride present at (2,6) has 2 qualities.

The Bride present at (2,9) has 2 qualities.

As we see, there are two contenders who have maximum qualities, one is at (1,7) and another at (1,8).

The girl who is closest to Sam's house is at (1,7). Hence, she is the bride.

Hence, the output will be 1:7:3.

Example 2

Input:

6 6

1 0 0 0 0 0

0 0 0 0 0 0

0 0 1 1 1 0

0 0 1 1 1 0

0 0 1 1 1 0

0 0 0 0 0 0

Output:

4:4:8

Explanation:

The bride and qualities are present at (3,3),(3,4),(3,5),(4,3),(4,4),(4,5),(5,3),(5,4),(5,5)

The Bride present at (3,3) has 3 qualities (i.e. (3,4),(4,3) and (4,4)).

The Bride present at (3,4) has 5 qualities.

The Bride present at (3,5) has 3 qualities.

The Bride present at (4,3) has 5 qualities.

The Bride present at (4,4) has 8 qualities.

The Bride present at (4,5) has 5 qualities.

The Bride present at (5,3) has 3 qualities.

The Bride present at (5,4) has 5 qualities.

The Bride present at (5,5) has 3 qualities.

As we see, the girl present in (4,4) has maximum number of Qualities. Hence, she is the bride.

Hence, the output will be 4:4:8.

Solution in C:

 
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
// Function to check if given indices are valid in the matrix
int isValid(int row, int col, int N, int M) {
return (row >= 0 && row < N && col >= 0 && col < M);
}
// Function to count the number of qualities a girl possesses
int countQualities(int matrix[][100], int row, int col, int N, int M) {
int count = 0;
for (int i = row - 1; i <= row + 1; i++) {
for (int j = col - 1; j <= col + 1; j++) {
if (isValid(i, j, N, M) && !(i == row && j == col) && matrix[i][j] == 1) {
count++;
}
}
}
return count;
}
// Function to find the suitable bride for Sam
void findBride(int matrix[][100], int N, int M) {
int minDistance = N + M; // Initialize to maximum possible distance
int maxQualities = 0;
int brideRow = -1, brideCol = -1;
// Loop through the matrix to find the bride with maximum qualities
for (int i = 0; i < N; i++) {
for (int j = 0; j < M; j++) {
if (matrix[i][j] == 1) {
int qualities = countQualities(matrix, i, j, N, M);
if (qualities > maxQualities) {
maxQualities = qualities;
brideRow = i;
brideCol = j;
} else if (qualities == maxQualities) {
// If multiple brides have the same number of qualities,
// find the one with minimum distance to Sam's house
int distance = abs(0 - i) + abs(0 - j);
if (distance < minDistance) {
minDistance = distance;
brideRow = i;
brideCol = j;
} else if (distance == minDistance) {
printf("Polygamy not allowed\n");
return;
}
}
}
}
}
// If no suitable bride found
if (brideRow == -1 || brideCol == -1) {
printf("No suitable girl found\n");
} else {
printf("%d:%d:%d\n", brideRow + 1, brideCol + 1, maxQualities);
}
}
int main() {
int N, M;
scanf("%d %d", &N, &M);
int matrix[100][100];
for (int i = 0; i < N; i++) {
for (int j = 0; j < M; j++) {
scanf("%d", &matrix[i][j]);
}
}
findBride(matrix, N, M);
return 0;
}
 

Alternate Solution (Brute Force):

scanf("%d %d",&n,&m);
for(i=1;i<=n;i++)

{ cnt++;
} } }
cnt=cnt-1;
a[k]=cnt;
k++;
} } }
for(k=1;k<=t;k++)
{ if(a[k]>max) max=a[k];
}
if(max==0)
{ printf("No suitable girl found"); goto x; }
for(k=1;k<=t;k++)
{ if(a[k]==max)
c++; }
for(k=1;k<=t;k++)
{ t2=0;
if(a[k]==max)
{ for(i=1;i<=n;i++)
{ for(j=1;j<=m;j++)
{ if(g[i][j]==1) t2++;
if(t2==k)
{ x[u]=i; y[u]=j; u++;
} } } } }
t1=u-1;
if(c==1)
printf("%d:%d:%d",x[1],y[1],max);
else
{ for(u=1;u<=t1;u++)
{ e=x[u]-1;
f=y[u]-1;
if(e>=f)
{ sc[u]=e;
}
else sc[u]=f;
}
min=sc[1];
for(u=1;u<=t1;u++)
{ if(sc[u]<min) min=sc[u];
}
for(u=1;u<=t1;u++)
{ if(sc[u]==min) count++;
}
if(count>1)
printf("Polygamy not allowed");
if(count==1)
{ for(u=1;u<=t1;u++)

printf("%d:%d:%d",x[u],y[u],max);
} } }
x: return 0;
