Given an array, print the Next Greater Element (NGE) for every element. // // The Next greater Element for an element x is the first greater element on the right side of x in the array. // Elements for which no greater element exist, consider the next greater element as -1. // // Example: // // Input: arr[] = [ 4 , 5 , 2 , 25 ] // Output: 4 –> 5 // 5 –> 25 // 2 –> 25 // 25 –> -1 // Explanation: except 25 every element has an element greater than them present on the right side // // Input: arr[] = [ 13 , 7, 6 , 12 ] // Output: 13 –> -1 // 7 –> 12 // 6 –> 12 // 12 –> -1 // Explanation: 13 and 12 don’t have any element greater than them present on the right side
