text: Find a Fixed Point ( Value equal to index ) in a given array | C # program to check fixed point in an array using linear search ; If no fixed point present then return - 1 ; Driver code
code: using System ; class GFG { static int linearSearch ( int [ ] arr , int n ) { int i ; for ( i = 0 ; i < n ; i ++ ) { if ( arr [ i ] == i ) return i ; } return - 1 ; } public static void Main ( ) { int [ ] arr = { - 10 , - 1 , 0 , 3 , 10 , 11 , 30 , 50 , 100 } ; int n = arr . Length ; Console . Write ( " Fixed ▁ Point ▁ is ▁ " + linearSearch ( arr , n ) ) ; } }
