Question

Write an algorithm (in pseudocode, with proper indentation for blocks of code in loops or conditional statements) that finds and returns the location of the first negative integer in a sequence of integers.

Answer 1

Answer :

Let code pseudocode in C++.

int firstNegativeIndex(int list[], int n) {
   int index = 0;
  
   for(index; index < n; index++) {
       if(list[index] < 0) {
           break;
       }
   }
  
   return index;
}

Explanation :

Here list is the array of integer and n is the size of list.

• first it make an integer index, and assign 0 to it.
• then it iterate over list using for loop
• if it find negative number, it break the loop
• than it return the index of negative number
• else it return n
