Extract 1D array from 2D array

#1

how can we extract rows from a 2D array?

for example :

let us say we have 2D array of size 5x3

1 1 1

2 3 1

1 2 3

1 0 5

7 0 2

I have to search for the row which contains elements 1 2 3

how can I do this ?

See I’ll help you to understand it in a better way. Suppose horizontal lines are row and vertical lines are column.
So your question is that which row has elements 1 2 & 3 . And answer for that is row 2, which is 2 3 1
So how can you find that is, iterate on each row using for loop
For(int I=0;I<n;I++){
____For(int j=0;j<n;j++){
______// check if a[i][j] in this row of I, has 1,2&3 in it or not
______//if not then check in next ith row
____}
}
I hope this would help you as I have explained it in a very simple way :slight_smile:

I try this
In this, I try to take one entire row at a time and print it
